Another option would be to pay the writer for just the Introduction (or Literature Review) of the longer project, or to pay for a short outline and proposal before ordering the full 50-pg project.
This is exactly how I started doing business with freelancewriter after I wasted a lot of money ordering a large project from a website that looked very professional. What I received from them was something ridiculously bad, it was useless in every way possible. I put my trust in freelancewriter to complete the same order even though I was still quite afraid and skeptical due to my bad experience. He suggested just doing the literature review for me first and what he delivered was excellent. Since then I have ordered around 5 or 6 other projects from him. Every project I have received has helped me receive outstanding marks. He is expensive but not as expensive as paying someone else for a useless project first before ordering the same one from him to get it done right.
