Don't take this the wrong way. Lemons is very inclusive of whatever bad idea you have.
But...
I don't think there are a lot of paid crew/driver positions available. This looks like you are looking for a paid position.
As I understand it, the best a crew-only team member should expect is entry, food, and booze over the weekend. The best a driving team member can hope for is entry fees less than about $1000 ($500-$1500 depending on the car) (I typically charge on the low end for A&D, but inflation, my car is slow, and and I haven't done this for a while). That $1000-ish typically pays for your share of the entry fee and some-ish of the consumables (race tires, tow vehicle maintenance, beer, etc.).
Teams with complicated structures are either more complicated or cost more. I've run with teams that amortize the cost of the weekend and somehow figure upgrades per team member that isn't an A&D and do some other voodoo math. That all sounds complicated. I prefer to keep my hobbies simple, so I just charge a flat rate that is cheaper than the amortized cost of whatever lunacy I am up to on a given weekend.
Usually teams that provide more of a full-service A&D charge more than me. My team is weird because the party is more important than the race, so there's that also. If the car is broke, then paying drivers often get a refund/discount.
I've also never been a permanent part of a team that has complicated ownership. I'm the captain of my team, and I can be a gopher on yours. I own my car, and you own yours. I'm happy to work on yours for free so it runs tomorrow as long as you are happy to do the same on mine (assuming we are at the same races, etc.).
I don't really get the "joint ownership" concept of some teams that seem to be fairly successful. In my mind, it is easier to be the benevolent dictator of the team rather than trying to herd some random collection of cats into collusion to make a racecar.
