There are a LOT of people doing their own comics. They publish them themselves, ever hear of King Kat?
Marvel and DC have their own artists, as do most comics publishers, however some of the independent ones do take freelance work. Check Wikipedia for 'comics publishers', it's got a list. There's a partial list here -
If you're talking also about putting the work up online, smackjeeves.com and drunkduck.com are two places that host a lot. Or you can do it on a Blogger account.
As for an artist - 90% of the comic is the artist's effort, only 10% is the script. You would have to pay someone to do the work. Generally it takes a full 8 hours to do pencil roughs, panel layout, the inking and lettering for one page. Add 4 more hours if you want it in color. Since most comic books have a 20 page story, that's 20 days of full time work. Rates vary from $150 to $300 per page for artists, the letterer is usually paid separately.

It's best to do it yourself, or find a friend willing to invest this kind of time into it.
