What products/services have big profits??

Im looking for something preferably in the computers/electronics/cell phones industry as that is what I am familiar with. Anyone have an ideas on a small business I can start by selling on buy and sell sites? I could also offer unlocking services for cell phones, but I have no idea where these people get all of these codes.

My husband and I have our own home based business in the telecommunications industry. Something you might want to take a look at. Sounds like with your back ground you would be successful in this type of business.
We've partnered up with a 15 year old world wide company. We have been featured in several magazines like USA Today, Success, Fortune etc. Inc 500 rated us the 22nd fastest growing company in our first five years. We offer services that people use every day and pay for anyway. Services such as Local and Long distance telephone services, Internet, Digital, Video and VOIP, Satallite TV, and all the major cellular phone companies like Verizon, T-mobile, Sprint, AT&T (Cingular) Alltel, Nextel, etc have partnered up with us. How many people do you know, or know of that has one or more of these services? You save people money on their services, put people on contracts through various providers, add lines to existing contracts, upgrade and extend their contracts etc. You'll have access to promo codes too. We are the world's largest direct selling telecommunications service provider. Everytime people pay their bills, we get a percentage every single month. There's a lot of money involved in this industry as you well know with your back ground. You can have a web site and do online selling, or person to person sales or both, like we do. The income in this industry is just incredible.

Your more then welcome to email me if you'd like further information.
