stock images selling website!

First of all let me clear that its my own project so decision is entirely upto me weather to go for it or not, and honestly it depends on cost of creation and maintenance. Actually I myself am a designer and photographer and have alot of stuff to sell. Ok the idea is to create something quite similar to [login to view URL] using same functionality perhaps "cloning the fotolia" would be better word. But I would like to add sections such as photography from different origins, I would like to include ethnic photograph such as eastern cultural images, models from India etc. there should be section for people precisely looking something from ethnic minorities. I am fully open to new ideas and innovation in my project.
