I really wouldn't expect you to get too many hits on this. The problem is that:
1. We don't know who you are. Not trying to be rude or anything like that, but you have to understand that Indigos are in trouble in the wild and are subject to poaching by unscrupulous people. Nobody that cares about the animals is going to just tell someone where to find them until they are sure of motives.
2. Nobody is likely to post that information in a forum like this where just anybody and everybody can find it. The ecosystem that supports Indigos is fragile. If 100 people read where to find wild Indigos, then go trampling around in the habitat trying to find them they will do some damage. We tend to be a little protective of these animals and their habitats....
That said, there are plenty of places in Florida where there are Indigos, including some State and Federal parks. Do a little internet research and you might find a starting point.
