Hi Rachael -
It's very hard to be sponsored as a local rider in an unrated circuit. I have her fables about individuals being sponsored by local businesses (like local flower shops, mom and pop diners etc) but very seldom large companies (cars, Equine related etc) for local riders. Mostly, you'll need to have great sportsmanship, an honest tongue, good personality and show on a rated level to get reignited attention. Additional perks for possible sponsors would be an influence on social media! Best of luck!
