I agree with guidfarr, I think trying to duplicate a business model like that would be difficult to do in a good economic climate. With the downturn in the economy there is a lot more competition in retail lately. I d suggest doing some more brainstorming and see what else you can come up with. I m doing a program now if you re interested in trying it. It s free to sign up and has different components that you can join or not join if you choose. Some components are free and some aren t (those that aren t free have a free trial period). The free ones have a more limited earning capability but can be used to build capital for the ones with more earning potential.The free component can also be used as proof that money can be made online before committing to options that require a monthly fee. If you re interested you can find out more information at the link listed in my source.
you can t hope to replicate an existing hugely successful business and succeed. that is tough. you need to fill a unique need or a niche in the market. perhaps a site similar to ebay but targeted at people in your area would be a better idea.
