This is something I never searched for. When I was 20 a local speed shop offered a sponsorship which I took because I got 10% over jobber prices and if we hurt anything we were given priority to shop time to get out racing again. At 23 my hometown bar asked if I would put his business on my car with I did so he paid for car lettering. I do get somewhat jealous of seeing friends get free slicks, free fuel, free engine parts, etc but if you set your racing up as a business you think a little differently.
