Great idea :-)
There is already a photography website with full steem integration around. It's called bescouted.com.
Maybe you can fork/license this work, cause it won't make sense to start from the beginning. He's on steemit @bescouted and @bescouted.com
thank you! I wasn't aware of this web site. The look is very similiar to how I'd like this site look. The one for stock photos would need more search and tags features. I'll see if I can work something out with them.
