Cheapest way to obtain lending licenses in various US states?

I'm interested in hearing from people who have bought lending licenses for businesses in the US in various states. Specifically, it would be great to know what third party services (if any) you used to and what the fixed cost (states fees) and hourly cost of the people you hired to do that work was. The state fees are obviously available on each state site but if there was anything surprising or additional costs that you learned along the way would be great to hear about that. Also I am interested in non-residential lending.
