New Plan for paintjob: Piece by Piece, does that sound dumb??

[TIMSPEED]

Well, I've decided, I'm gonna save myself the labor costs, and take my truck completely apart, to have it painted, then I'm gonna put it all back together. Should be easy really. What I'm gonna do is...(When the weather won't rain for at least a month...)
1.) Pull bed off and put it on a few pallets
2.) Pull Cab off and set if on pallets
3.) Pull the doors and fenders off and throw them away (both doors/fenders are completely rusted out; but I've got NOS parts for them)
4.) Take the hood off and set it next to the rest of the parts
5.) Rent a flatbed trailer, and take all the parts down to the local paint shop (with prior appointment)
6.) Get all the new painted parts and put it all back together

I am choosing to do it this way, so I will be able to get the firewall and bottom of the cab more completely...or when the shops paint trucks, do they take the cab and bed off? I know they take the bed off, but I want the cab off too, so the firewall can be nice and clean.
