FWIW....
I work for my self and I use rally as a marketing and advertising tool. Like Dewalt does w/ NASCAR. Lots of European rally fans in high places in my industry. A % of my rally cost are expensed as business deductions, which, IMO, is far better than trying to get any sponsorship from a small game vendors (ie <$10K per year).
I see many guys, (who do not have the opportunity to self sponsor), spend hundreds of hours courting sponsors only to gain a thousand bux in discounts and free parts/services. Was it worth the time...? And then there is the big game who, if they sponsors you, they own you. I know one team/guy who had a very good sponsorship package, worked his ass off to get it and to keep it: new paint, new logos, more travel.... every weekend at the sponsors call for some store event/promo, then got dropped the next year. Saw Travis an Ken this weekend with camera crews incessantly in their faces; while eating, blowing nose, scratching ass... But I suppose those may be good problems to some people.
Keep good financial records, account for all that is rally as if it's a business, know your cost. That way if you are fast enough and charming enough for TV, you'll know what it cost to campaign a year on a national basis.
You can incorporate your rally team, but not sure what that will gain you over good insurance. Do not borrow for rally, nothing more than 30 days on a credit card. You are not going to qualify for non profit or not for profit status, unless you can claim red-mist as a religion
