I didn't have any more than that when I got into it. I just called up the 2 local companies I knew of and asked if I could train to do it. One of them was willing to train and the other wasn't. So they will probably listen to your story at least, and if they are really busy consider training you to do their particular system. If they are not busy or in need of help they are going to either pass or perhaps try and get you to pay for your own training somewhere else. I would be leery of buying more than a few hours of training for an operation they should train you for. Set a limit on it and if they waffle after the first few hours are complete in your paid training, consider it money lost and walk away. There are a bunch of shady banner tow training outfits in Florida also, I would avoid those. Realistically there are a lot pilots on the street now and I doubt you are going to see much action but there's no harm in asking.
