We don't know anything about the tax laws in Mexico, but here in the US, whatever we give to a charitable organization is tax deductible, and that is the main reason that we formed our Foundation. It allows our money to go much further, and land owned by such organizations is also not taxable. Do you have similar tax laws in Mexico.
Also, do you have a web site? If not, would you like one (free of charge)? This would hopefully give you more publicity for what you are doing, and maybe get you some of the help and support you are seeking.
