i'v used smokers in the past but not on a big scale like this
i have a Bullet smoker it doesn't hold a lot of meat ...
redneck cooking is an art forum the best way to go about it in my view would be find someone with a smoker that can handle that volume of meat and can handle that volume of cooking
i know from using a small smoker the big ones can be tricky to keep at temp if you never used one before
i would say find someone on HF thats going that is seasoned in big smokers
or hire someone to do it... i know up my way once in a while local fire co. will do it for a price but not sure about that area and it's hit or miss .. or see what it would cost to hire Shug to come out

also another way to go about it is get pork butts and do it in crock pots... yes i know it's not "Smoked" but i have done this way before and it came out really good but we would need a few crock pots
just my .01 ....
