Myself and a friend have a good idea for an online marketplace (Bringing together uploader and customer for a niche digital product) but I need some questions answered before we proceed. 1. Are there any Wordpress themes available for an online marketplace? or is it too complicated? would we need to get a website created instead? 2. How would I go about taking a commission from a sale of an item? 3. How do you also take a "selling fee" from the final price? 4. What "Must have" things would people suggest to have in a online marketplace (Allow user reviews etc) Any answers would be appreciated.
