Hi Hanoch!
Welcome to our passion. One suggestion for you would be to join your state club. In fact, I think Florida has two clubs, if I'm not mistaken. Once you join, you will probably get access to the club's membership list. Then, you'll be able to find some folks around you. However, most potential sponsors will want to get to know someone before "offering" to sponsor them. Your chance of getting someone to agree to sponsor you via an online request isn't very good. Good luck with your search and once again welcome to our obsession.
