Business Idea: Be the next generation Avon lady by selling Avon’s sister company called Mark which is focused exclusively on teenagers and women under 30. Mark Girls roam around dormitories and sorority houses promoting beauty products and fashion accessories for a commission ranging from 20% to 50%

What makes this different from Avon is that Mark Girls can promote these items via social media sites such as Facebook, iPhone apps, twitter, MySpace etc. As of this writing, there are more than 40,000 Mark representatives in North America and most of them are 18 to 24 year old women.

Startup cost: $20
