Thanks, Dylan. I'll have a look at kasamba.com.
As for posting my email address, I never thought of that, though it's not my personal email so if I get spammed I can always chuck it.
Do try Elance, though. They have hundreds of professional writers, and the site's really easy to navigate, with each writer subscribing to types of writing sections, such as article writing, copywriting, editing, etc. Probably essay writing's there, too, though I haven't actually looked at that, because to me it's just one type of writing service among many possibilities.
I also subscribe to freelancejournalism.co.uk which has hundreds of professional writers and they're pretty wide-ranging in their skills. From what I can gather, most of them have academic backgrounds and are happy to take any work that pays - plus if they disappoint they can't hide behind a company, can they?
From what I've read on this site, it sounds like you're better avoiding these essay writing companies altogether. Before I (accidentally) found the essayfraud site, or whatever it's called, I very nearly submitted my bank details to one called Academia.Research or something like that. Then I noticed there were no links for students looking to have essays written. Also, there was small paragraph which said something about "what we sell is a book....". I emailed them and queried these two things. They said they didn't sell a book and gave me an email address for students looking to have essays written, but I couldn't find this email link on their site. When I found the essayfraud site, there they were, listed as a scam company. I have very little money - I'm working as a cleaner in a school right now to pay my rent - and I dread to think that I nearly gave them my account details.
Anyway, thanks again, and I wish you all well in your studies.
I'm going hop off now back into the ether.
