Welcome to the site!
I grew up in the Tampa Bay area (Clearwater) but an now in Orlando for college.
One of the biggest things for me is transparency. I want a breeder to be open and honest about their animals and practices. I want a breeder to be available for questions as you pointed out, and most of all I want a breeder to be completely above the table when it comes to complying with local/state level/federal rules about owning/breeding/selling exotic animals (we have some interesting ones here in florida) I think that a good reptile breeder should be active in the reptile community, as well as in his/her local community showing people that reptiles aren't something to fear, and that the people who own/work with them aren't crazy lunatics, but passionate people who can see past the societal misconceptions about them.
