Two e-commerce websites to be designed

I am looking for a freelancer to help in designing a creative website for me. These are for two businesses I want to start:
One for selling second hand clothes
The other for selling exquisite African carvings

The aim is for every transaction a % goes to a charity where does clothes or carvings were purchased from. The website also has to be close to nature and environment friendly. How that can be done I really do not know. That's why I need someone creative.
