The cheapest I have seen it is right around $200 and Chamberlain high school in Tampa hosts that class. As for the license, once you get the certificate or card you can just go down to the DMV and present that card and get your license.

As for the registration, I believe there was a new law passed saying you had to have your endorsement before you can purchase a bike from the dealership, so I dont know if the same rules/guidelines apply to needing an endorsement to register a bike.
