A couple days ago I talked about how ebay is one of the best businesses to start because so little upfront money is needed. The problem though can be finding what will sell and a good source for things to sell.
Another angle that I have been seeing more and more is becoming a seller for other people. So many companies have old equipment or an overflow of product and so many people have an attic full of junk they want to get rid of. Most of the time both of these people dont have the time or know how to sell these items on Ebay. Why not offer your services? Take the product off their hands, sell it and split the profit. It is a good stay at home job and a good service that a lot of people could use.
