Meaning, add it to your choice list, talk to the company, consider their "promises and guarantees", then decide on your own.
Excellent advice. As I've said in other posts in the forum, phone and chat communication is often helpful. Email is fine, but most anyone can prepare a stellar email to entice a customer. It's the quick response type situations that help pinpoint the small things that indicate a company may not provide the level of services a specific customer needs. When communicating solely via email, pay close attention to the details. How attentive is the responder? What is his/her knowledge level regarding your project or needs. Of course, I am not saying that all customer service reps will be knowledgeable in your given area, but they should be professional and willing to say "I am not sure, but I will find out!" Companies that promise and guarantee everything are most often the main ones who can't fulfill even a fraction of their claims.
You cannot blame anyone but yourself if the deal goes south or if the paper you receive is not what you expected.
Equally true! By the time a student reaches the college/university level, he/she should know enough about their respective course of study to know whether the "model" received is up to par. At the very least, the student should be able to take an "okay" paper and tweak it to fit his/her needs. One of my pet peeves is the lazy student. Not a student who sincerely needs help, but the student who orders an essay (or all essays in a given course) and then asks a million questions regarding what the essay is about instead of reading the essay. While it's okay to seek help when you need it, it's important to also review what you receive. You have to learn the material that is being provided. The essay writer can't put knowledge in your brain and they can't (or shouldn't) take exams for you. At some point, there has to be initiative to succeed on your own merits. The same premise applies to seeking and selecting a writing service or freelancer.
