Calling for support or advice.

The last four years I was employed by a company that went under due to the economy.
The last eight months I've been looking for anything to support my family with no success at all.
I've been thinking of a way to come up with an original way to make money on my own and believe I am hatching a really good Idea that would be dealing with offering a new twist on Pre-paid cell phones. I just need to find out about how to go about contracting the airtime from a cellular carrier...Any ideas? I truly believe this would revolutionize the cellular phone industry.
