There's a thread on this subject somewhere in the arts sections.
Basically, almost all photography jobs require you to work with people very closely. There's the model, and assistants, unless you do family portraits which means interacting with complete strangers who may or may not be motivated to listen to what you say.
It's pretty rare to get a career in art photography. I was at the Pebble Beach Concours last year, and saw a lady photographer taking pictures. I told her (in a rare moment of bravery) that I want to get paid for taking pictures of cars. She replied 'good luck' because antique cars are just one of many subjects she takes pictures of.
Which is not to say it's impossible.
I'm posting my best pictures on Deviantart, and that website is a real eye opener as which pictures get the most responses. (Here's a hint, beautiful women with no clothing get the most comments.)
