As an amateur you cannot have sponsors. If I were you the best thing you can do is to just tell family and friends what you are doing and ask each of them if they would be interested in donating $10-15 to you toward your tournaments. Then send them all thank you cards with some tournament photos when you are done. Typically sponsors want you to do something for them as well. It is not just "oh hey I want some new equipment, and then for you guys to pay my entry fees" because that does not benefit them. Asking for donations from friends and family is your best bet.
