I can't tell you anything about your local area, but in general it's best to offer something dirt-cheap to attract attention and then to have more expensive upgrades available. Maybe five bucks for a 4x5 print and then go up for an 8x10 or an 11x14. At that point you can offer just the print, a matted print, or a matted and framed print on an ascending price scale.

I don't know if you have the Michael's chain over there, but I use them for non-photo supplies like matting and framing materials. Excellent selection at reasonable prices, though if you end up needing a lot of these materials there are better deals to be had through wholesalers.

Post all of the shots on the site and let your customers pick them out. If you enjoy being out there and taking the shots in the first place, it's a good way to earn a few bucks. If you're both persistent and lucky, it can turn into an excellent income.

But make no mistake, if you don't treat it as a job, it won't reward you with that income. This is actually true of any endeavor, not just photography...
