the photo biz took a dump when the web slowed up, Amazon crashed etc . . . all those guys were shooting for mainstream websites . . you know pics of assholes drinking coffee or what ever for ads and such. now most photography is work for hire and not really licensed anymore, and now that every joe blow has a digi cam and printer it's even harder to sell prints . . . Go to
http://www.dpreview.com/ and start stalking the forums, you'll get a good over view of what's going on . .. BTW this is not intended to discourage you in any way . . . Get busy bro . .
