The truth is that one cannot make any recommendations regarding academic sites for writers to work for simply because we all different experiences as freelance writers contracted on a per project basis by these companies. What is good for Adam may not be good for Eve and vice versa. The best thing that you can do is go through the whole rigmarole of applying at various companies, passing the assessment tests, then trying them out. Word of warning though, if they say you will have to provide a number of free essays before they start paying you, or that your salary will be withheld for more than 2 weeks prior to releasing your salary, run for the hills. Each version of the company is not a company that will ever pay you.
You are the only person who can tell if working for one company will be good for you or not, depending upon your work experience with them. Additionally, if the online interface for the ordering system is one that you are comfortable using and if the bidding system per order makes sense to you, those could be major considerations for your deciding to work with the company on a long term basis. Of course, the pay schedule system is the most important consideration.
Your English level is nothing more than pidgin, so it is understandable that you would not pass any of the writing exams that even the worst third rate academic outsourcing company could provide. Your claim of having the ability to write such a highly technical paper such as Business Management papers is nothing but an exaggeration on your part. Boasting about your non-existent abilities in an effort to keep up with the real and reliable academic writers at this forum.
There is nothing legitimate about your post. I am wondering how you managed to con the middleman into hiring you. He must have even worse English vocabulary and writing skills than you do. I don't believe that you have a future in this industry. I also think that after the post you made, and the responses you received, you figured out that academic writing is not the career for you and hopefully, you set off into the sunset, in search of a career more appropriate for your skills.
