350/700r4 hook up

[66chevyjunky]

Guys, I'm planning on buying a new 350 crate and a new700R4 to complete the drivetrain on my ride and was curious about hooking it up myself. Aside from needing to cut the drive shaft, how difficult is hooking the two up to each other and to the truck? I'm pretty mechaniclly inclined but not sure if i should leave this up to a professional. And if so what am i looking to spend on labor(ballpark) for someone to do this for me, assuming i walk in with the engine and tranny? Any advice would be much appreciated. THANKS!
