This new mindset is nice to see in contrast to prior posts.. you're on the right track.
Contrary to popular belief, Lemons is expensive, has some incredible drivers, and some of the best wrenchers/engineers I've ever met. Compared to [that other series]... Lemons has a much wider range of experience and talent, but on the higher end of that spectrum, the drivers are better, the wrenchers are better, and actual engineering is invested into the vehicles than just throwing money at them. All of this is to say that I would be careful about overpromising your experience and capabilities, most of the more experienced guys will see right through it.
What makes you appealing is your eagerness, willingness to learn, youth, and energy. Be careful about overselling yourself... ability to drive a manual, experience with SIM racing, and ability to sustain high G's without passing out (FYI, unless you have underlying health problems, G-forces experienced during a budget enduro race are nowhere near black out territory) are not relevant selling points. Are you willing to help clean the shop? Do you mind vacuuming out the rat poop at the start of a new build? Are you willing to run crew for the first few races before becoming a driver? I think most of us around your age cut our teeth into the automotive world by sweeping floors, organizing shops, and changing oil. We love having new people in the community, and the best way for you to be appealing would be to have a mentality more along the lines of "hey, I can do basic car stuff, no job is too big or small for me, and I want to help you." I don't know of any teams that would be willing to "sponsor" you... no money, no drivey. However, there may be a team willing to take you in as crew that can provide their experience and knowledge in exchange for your time.
