gonna throw my
in on this real quick.
For starters, your not out as much money as your suggesting. The equipmnent is something you can use again and again and again with different models so you can't really include that in the loss. Your not out on money for the model because you have her content, and I can tell you this, its not the amount of content you have, its the quality of the content. I do not see where your out money.
The situation did not work out with that girl, get used to it and move on, launch the site, use her as the spokesperson, then add other content...its not hard. If you have good content use it, if you dont, toss it and start over. There is a million things you can do, dont focus on the one bit of content, this business is a bitch, like most businesses, stay in it long enough and your going to get fucked over, stabbed in the back and ripped off.
dont worry about lightspeed, dont worry about the model, dont worry about the cam place, focus on YOUR goal and get on with it, you sound like life is over, you do not have to follow other people examples of a "single girl site", do it your way and dont even look at other sites untill yours is done the way you want it to be.
