wireless internet card and routers

Hello everyone, I'm new to the forums and this is my first post. Nice layout by the way. Anyways, I was wondering if anyone knows if it's possible to use a verizon wireless internet card over a network and share it. I was thinking there might be a way to get the computer with the card appear as the modem for a router and then use it to transmit the internet to other computers. The only thing close to this I've come across are the new 3G routers, but they're out of my price range.
