I've been asking around and it seems that there is a guy who tried to do something similar years ago. I've contacted him and now I'm waiting for his reply. I was told he even manage to convince the local government to subsidy the idea . GA apparently is welcome here. Also the local community with money to spend in this kind of stuff seems to gravitate toward boats, or horses there is no much else to spend the money on...so perhaps introducing aviation to a larger scale could give them a good excuse to spend the money on something else . I am thinking on microlights or ultralights. I even saw a field good for this purpose, it hosted a big airport decades ago. I visited it and there is nothing built on it. The old control tower still there and so on, with a few adjustments could host general aviation planes.
thanks for all your advice
