I can't offer you much more than what the others have mentioned but I would like to add the following link ...

Zack is a professional editorial photographer and has a section of videos on his blog called "Critiques". He has a lot of pointers and ideas you might find helpful as you start up your business and refine your web presence.
Good luck!
