If you want to get sponsored you need to join a team, if they have any in your area, so that you can get in a league.  If not, you need to play in some tournaments that are held in your area.  If you are as good as you think, and you win and advance up the chart, you will make a name for yourself and you can hone your skills to become unbeatable.  If there are no tournaments where you play, start one.  It is not hard, and you could play and charge a small entrance fee, to give to charity.  Why?  Because giving to a needy cause is important.  It proves that you think about the less fortunate, and you will get some recognition for being a selfless good sportsman.  When you support a charity, it brings out the best in other people too, and as people are drawn to this type of event, you will become known.  You get the idea, I am sure. You have already figured out that racquetball is a game of strategy as much as it is eye-hand coordination.
