How much do you want to invest in this. The reason I ask is my sis just started a photography business 3 months ago and its growing like crazy!!! She is even having a studio built b/c she is getting so much business. She has a digital Cannon...actually 2 of them but one cost $900 and on like $2500. The digital is wonderful b/c you dont have to worry about taking to many pics since you can always delete them.
Here is her site
www.littleroyalty.com
She also has a blog under the same name, but i cant remember her address. If you have any questions she LOVES to help out. Her xanga is
www.xanga.com/emcaymom . that site is devoted to ppl asking questions.
or you might try photography.com. i was interested in getting into the business and found tons of info there!
