Wanna try racing and need some advice

I just bought a 1000xp 2 seater. I used to race quads til I lost my leg in a auto accident. I would like to maybe try and run the rzr at a few races, an attempt to get the same adrenaline rush I got racing before I lost my leg. I have read the score and gncc rules for getting my car ready. My question is what is a good series or race that is more for amateurs and beginners?? Who is a good person to contact regarding the series??? I live outside StLouis MO in southern IL. My cousin has an 800 and is also very interested in doing this with me. If I can get some help finding a good series or race for my skill level ( which is none) then I can make sure the car is compliant with that particular race or series rules. Not really wanting to travel 2000 miles, but 500 to 600 or 5 to 6 hours would be cool. Any help would be greatly appreciated. Just wanna race without dropping $30k and cutting my bike apart. Just wanna have fun! Just need a point in the right direction.
