It *is* a good idea. People would probably love to buy prepaid phone credit or phones or whatever with BTC. I'm not sure someone who doesn't capitalize sentences or use apostrophes is quite qualified to manage a crack team of coders putting such a service together.

I know what's up with your secure certificate, since you host at DreamHost, and I used to work there and wrote their secure certificate billing system. You have secure hosting set up, but the "real" certificate you ordered probably hasn't yet been written up by the actual Certificate Authority (which isn't DreamHost). If the code I worked on still works, it should show up sometime in the next couple days and be automatically installed on your site. If it doesn't, don't hesitate to contact support.

If you actually want to sell cell phones for BTC, I would recommend you set up an OpenCart install then install and configure the MyBitcoin SCI plugin for OpenCart. That will give you a fully functional online shopping-cart-driven store, where you can set prices in dollars and have people pay in Bitcoin (sent to a MyBitcoin account), converted at the current exchange rate.

Once you have a functional site, you'll probably be in a much better position to hire developers.
