well... IF you have the money and the know-how (that includes web-developing and programming in Java, MySQL and the rest of things - it's best if you bring as less people in on the business as possible) you could make a warehouse filled with electronics (PC/TV/Phone/Blenders/Toasters and what-not...) and a website to interface with your inventory and allow people to buy them.... also some refurbishing service would be nice... and profitable on the long run...

GOOD LUCK!
