As an experienced editor, I can tell you for a fact that it is a difficult profession to break into--especially without a related degree. I have degrees in English and History, with a strong background in grammar and spelling. Those are key elements if you want to build a reputation as an editor.
The work at home aspect is very nice, though. Just don't let people take advantage of you. You'll find plenty of writers who want you to "take a look" at their books, but don't want to pay for your time. If you want to work for free or you're looking to build your reputation or client base by editing books just to get your name on a cover, that's up to you. I wouldn't make a habit of it, though.
Fortunately, there are sites now that advertise or broker editing work, proofreading assignments and other types of freelance writing gigs. The Craigslist is one of the better ones. Do a web search for that and then email some of the registered freelancers on the site to see if/when they get paid for their work. Some websites WILL rip you off, so be careful.
Also, if you really intend to become an editor, you must above all else be an expert speller and grammarian. There is no wiggle room for errors. There is no excuse for English not being your first language, either. In short, there are NO excuses for typos or misused words like "it's" and "its" or "affect" and "effect". You cannot rely on spell checkers or even Word functions that check your grammar. They will NOT catch those kinds of errors.
Okay, lecture over. Good luck finding work. It's tough, but it sure beats digging ditches.
