You have four post? Most people wont even trust you. Also if you do a paper for someone how do they know if you wrote it or just copied it off the internet? I think you should do some for free and then start charging. Also have a set rate for each page. Like one page is 50 cents 2 pages is a dollar. Something like that. To me this is just something throw together, and maybe even a scam. Just trying to help you.
Umm well report him in the scammer section, also maybe you should have read my post? I stated that he might be a scammer. So sorry for your loss, but you kinda walked into it yourself. Always do your research.
