Auto body repair & detailing: rust, seam seal, body filler

Question
I have a 1999 silverado, the extended cab part on the drivers side has become rusted out. could you give me an estimate on what the cost would be to fix that the right way.

Answer
COst of repairs is difficult because repairs cost differently in different areas. They make an aftermarket pnal that will replace the bottom of the door skin that should cost about 45.00 or so from a company called Keystone. Also look on ebay. The require that you remove a section of the old door skin and wels or glue in the new one. Do a minor amount of body filler work and seam seal the inner panel and repaint.
