Business that earns 80% Profit Margin

Anyone interested in 100% cash business and up to an 80% profit margin? I wish my hubby’s internet café earns that much. We are in a 100% cash business but 80% profit margin is way too far for us to reach. Maybe we should venture into vending machine business. I just found out today from multivend that owners of vending machine earns that much!

Multivend, LLC was established in 1990 and has become one of the leading bulk candy vending machine manufacturers in the United States. Since the beginning of 2003, Multivend has established a worldwide presence and welcomed almost 9,000 members to the Multivend Family. I wonder whether they have branch here.
