An Economic Engine Supporting Blender

I have been considering building a consumer focused website that would allow digital artists to sell customizable videos and e-cards. This would provide a simple business model for artists and would provide a funding for Blender. The main business would provide funding for Blender as that would enable more artists and better quality for consumers. I recently found a website with a similar model but I am not sure of what technology they use in the back end. Image something similar to the below sites but that uses Blender and clud rendering and is open to artist submissions with a share of the revenue. Is anyone already doing this with Blender? What are your thoughts?
