Is there a possibility of someone with more PC savvy then me starting a website where we could post digitally created buildings or pictures of buildings for exchange? Seems like an exchange of, “I need a two story building made of brick” could be followed up with submissions to the files for downloads along with thumbnails of the buildings.

I hope this helps.
