I am a 14 year old junior tennis player who has been as high as number 1 in my region (for 4 consectuive months) and 101 in my usta section. I would like to start playing ITF (international tennis) tournaments. In order to do so, I would like to obtain a finacial sponsor in order to help me with the costs of traveling, equipment, and coaching. In return, I could wear a patch of the companies logo on my shirts, they can even provide me with shirts just with their logo which I can wear to school, practice sessions and tournaments. Any ideas on where to apply for some that can actually help me out? Thank you very much in advance.

Thank you very much for your answer, but can you give me a fex examples on what companies to ask? Thanks again!
