Developing some old film

Hi Chuck. Same old song and dance, I'm sure. First, I have an 8 mm Brownie MOvie camera with an f/2.7 lens, and a Brownie 8 movie projector, model A15 f/1.6 lense. There was an old reel of film in the camera, of which I would like to try and develop. I probably screwed it up by exposing it to light, but....Who do I send it to, and app. how much do you think it might cost? And how do I get some moe new film for the camera? Do you know of anyone here in the Denver area that fools around with this type of equipment? Thanks. John.
