I was going to tell you right out of the bat that Evolution diving is the best dive shop in the world. Great little shop, great management, awesome dive guides that actually know how to dive (in trim, in control, showing badass technique), who know not to bang on stuff and just point calmly at the stuff they wanna show you so you can enjoy the dive, with badass instructors and badass technical diving facilities. And I could probably recommend another two dive shops Ive dived and liked over there.
But then you decided to state you want to pay whatever YOU feel is fair to pay. You don't give two craps about the costs of operating a business where you are going, or the effort put into having well trained staff, or good boats, or a fantastic compressor setup. You just care about what YOU believe in your head a fair price should be. In that case, I can't recommend ANYONE, at all. You just have the wrong attitude. I really would love to understand what "reality" is according to you? Whatever pleases you?
Good luck.
