it won't harm the writer if he/she sends in at least the first 250 words of the paper to win the confidence of the customer since both of them are new to each other.
That might sound sensible to you if you're very new to this business and/or you just dabble in it to supplement your other income, maybe writing a project or two every month or so. It also might make sense to you if it takes you several days of work to write a relatively short project the same way it takes students that much time to write their projects. I'm telling you, as someone who's been doing this fulltime for a living, (probably since you were in high school and maybe grade school), that when you write a high volume of projects, what you're suggesting just isn't practical for at least several specific reasons:
1. I write most projects of roughly 10 pages or less in one sitting, or (at most) in several sittings in the same day. I don't have time to sit down on two different days for a short project waiting for payment for the rest of it after writing "at least the first 250 words" and I don't have time to sit around checking to see whether the client has paid for the rest in between writing that 250 words and finishing some little 5 or 10-pg project that I'd otherwise complete in a few hours from start to finish.
2. For every new client whose first project I actually book, I receive at least 2 project inquiries. I'm way too busy writing booked projects to be able to write "at least the first 250 words" for every new client's project inquiry. If I were to adopt (and advertise or publicize) the policy that you're suggesting, virtually every prospective new client would request a "sample" before deciding to use me. If you'd ever actually done this work fulltime for any length of time, you'd know exactly why nobody but a fledgling writer would ever agree to do this for every prospective client who requests it.
3. When you do this fulltime, you already have to spend a
lot of time responding to new inquiries and answering questions from new prospective clients. To add the task of providing free samples for all (or many) of those inquiries would be impossible without cutting into your work time and income.
4.Your suggestion doesn't even provide any safety for the client. Anybody devious enough to create a whole scam website that works to attract customers in the first place is also quite capable of coming up with 250 words on most projects; or they could easily outsource that task to a real writer and pay for a single page to send prospective clients to trick them into paying for the rest of the project to steal their money. Anybody who's actually been writing for a living for any length of time can tell you that he or she has definitely been contacted many times by apparent scammers of exactly this variety. In fact, I've previously described on this forum how I knew someone was trying to do that because he slipped up and forgot he was pretending to be the client in his emails to me (asking for a free sample page or Introduction chapter) or because he accidentally included some of his communications with his (other) intended victim in his emails to me.
5. As Major pointed out, a clever client could easily come up with 4 or 5 different sample requests to try to get as many writers to provide much of a an entire project for free. If you'd ever actually done this for a living, you'd know that sometimes it's the clients (or people pretending to be genuine prospective clients) who try to get something for free from legit writers.
I'm not saying this to insult or belittle you, but it's very obvious to me from your 10 posts here that you haven't ever actually done this kind of work, much less at the volume necessary for a fulltime living, and that you're
very new to this, at best . Let me suggest to you that you're just not in any position to be arguing with or proposing your theories about how you imagine this works to anybody who's a bona fide veteran of this kind of work as a fulltime occupation, because you have no real experience doing this for a living. Your profile here is less than a month old and I imagine that represents the approximate amount of time that you've been dabbling in this profession. That's fine; but you should be reading and learning from your much more experienced colleagues here instead of presuming to tell any of us how you imagine this business works.
As I've already tried to explain,
someone has to take a small risk initially and that's unavoidable: it's either the client risking payment for a very short project or the writer risking wasting his time and energy writing a free page for clients who might just be testing the waters or sending the same email to several writers. The way for clients to mitigate that risk sensibly is to use resources such as this forum and its search function, as well as other online resources, to research the writers they're contemplating hiring instead of expecting any writer who already does this successfully at a high volume to provide free "samples." I've also already explained (many times) that clients should try out any new writer with a very short project before commissioning a longer project from a stranger. You could even offer to prepay for just 1 or 2 pages if you're that worried, but unless you want your project written by a
very inexperienced or very desperate or strictly part-time, fledgling writer, asking for "free samples" is a non-starter and a very quick way to weed
out most of the very experienced writers who most clients
want for their projects. Frankly, most of us are often too busy to provide a single
prepaid page for every new client; but at least that request is more realistic and appropriate because it limits the client's risk to a single paid page and doesn't require busy writers to put in time working (possibly) for free. It also probably eliminates the possibility that the client has sent the same email to several writers and hopes to try to "negotiate" prices or go back and forth with several writers after each writer has already spent time writing a sample page.
This pretty much guarantees that only the most inexperienced and desperate writers will even consider taking on your projects. Most writers who've actually been doing this for a living for many years just don't have time to write "at least 250 words" as a "sample" for every prospective client. We're busy enough just managing our work schedules and responding to incoming inquiries from clients who already understand how this works.
