68 burb with 6.0l drivetrain

[six8burban]

1968 3dr suburban (2004 6.0lL drivetrain) this is a project that I never finished. Vehicle is not drivable front is off ( see pic). Engine drivetrain and drive shaft connected and ready to go. stainless steal brake and fuel lines are connected and ready to go. New Front big disc brake kit, new brake booster and master cylinder. New quick ratio gear steering box. New Stainless steel gas tank. New springs and shocks and body bushing all the way around. Front and rear sway bars. ecu was mapped by street & performance (http://www.hotrodlane.cc/) headers and wiring harness also from S&P. Custom radiator and shroud with stall electric fan. Did not put front back on because Driver side rocker panel, and both cab supports need to be cut out and replaced.
So now it awaits a good body shop this is far as my skills take me. To replace driver side rocker and cab supports how much should i look to spend? IF I SELL WHATS A GOOD PRICE?
