I also find this sites rules kinda bizarre...you can trash a site all you want, but not recommend it. Having said that, I did find a legit US based service, though they are expensive (40 a page for low level stuff) and I'm in the processes of finding a cheaper one. I wish it was easier than this, a cheaper might equal ESL which should be avoided. In general I think that all recommended services here are well known so it all comes to making sure the writer or service has is qualified enough in your subject area.

Why is it so hard to have a list of verified sites? That's all I'm asking, I'm not trying to break your frikin rules.
