It's already been mentioned but giving them the discount (provided you don't immediately need the revenue) in exchange for a 24 mo contract seems ideal. I believe the longest you can contract would be 24 mos (12 mo w/ 12 mo auto renew but it might be worth asking an attorney/search a bit online. I would also ensure you can use their name to leverage into additional customers. Congrats by the way, this seems like a nice problem to have :)
