Presumably. Personally, I think it might be a bad idea for a writer here to hire an editor to post their work here. Going so far as to say I would definitely try to talk them out of it, it's pricy and the return for posting their stories for free isn't worth it. A lotta folks on this site would be happy to give it a valid critique for free. If they wanted to upload to amazon that would be a different story though.
That said, I'd tell your friend that it'd be a good idea to really give a thorough overview of their credentials so the administration knows they're legit. I know that there are some sketchy freelance editors out there, and most writers should be pretty wary of being taken advantage of.
I don't see why not. I vaguely recall seeing people do that in the past and there are certainly people selling cover art commissions in the art forum. There's no good forum for selling an editing service though.
