Chris, I kind of agree on the cost versus content thing. But feet are a niche so the laws of supply and demand raise the cost of the material I'd think.
Going on your thoughts, then odd insertion with no face showing should be cheap as well. It's not sex and it's no face shots in alot of cases. Price THAT content!
Email us with your ideas and prices that you think are fair etc.
We might be able to work something out.
