Buying homemade explicit videos

Hello, we are a new site looking to establish our foothold with homemade explicit videos. We are currently looking to buy videos which are self shot. The videos need to be of a minimum length of 5 min and we offer $100 for it. For each additional minute, we offer an increment of $10. If there is a view of the participant's faces, we plan to offer an additional $500 bonus, if the participants are ready to shoot a total of 5 videos.
