I think that it is a good idea, but don't forget that Florida banned these snakes a long time ago. If you are taking peoples' unwanted pets, you could be caught, fined/arrested and have your records subpoenaed for the information of the people who turned in the snakes. Even if this didn't happen, you still wouldn't be able to sell the snakes in Florida or take them to other states.

If you are going to take the snakes out of the swamp, that's just a bad idea. Period.

Either way you'll end up stuck with a warehouse full of snakes that you're going to have to kill or somehow take care of. I'd try a state other than Florida, but if you insist you might talk with the state government to try and get some kind of deal where you send them out of state in compliance with the Lacey act.
