Before you pick a vendor you may want to consider the type of system you put in. 410A is being phased out and may cost thousands if you have to replace it in future repairs. Not sure if it is an option yet in Florida.
May be worth holding off a few more months.
Also a variable speed compressor is more efficient but more expensive. Still may want to consider it because it doesn't have to be cycled on and off constantly so you won't have the blast of hot air every time it starts. And with a variable speed fan you will have excellent humidity control.
