New bed or bedside is in order. You should be able to find a cheap bed. But nobody in their right mind would take off all pieces, window trim, tape, prep, and spray the entire truck for anywhere near the $400 mark.
no i said you do all that for the 400 bucks then let them spray it me i would get a copresser and spaygun and do it myself (good thing i work with a Body man that owns his own shop with paint booth)
i got mine for 300 36 gallen tank 150 max psi takes it about 4 min to fill up form empty a gun will cost you around 100 for a ok one the main point is when you get done you will have a compresser and gun and not just a paint job
