I would suggest doing cheaper sittings for friends and family so you have something to show clients. Craigslist is good but you need a portfolio 1st. If you are on Facebook start a facebook page where you can post some of your pictures. Its a good way to get your stuff out there and show people what you are capable of. Photo software Adobe photoshop has great stuff, as for cameras you cant go wrong with a nice Canon or Nikon. I have a Canon 30D which a lot of my pro friends use (which was why I bought). Good luck!
