If all of it is missing, bid extremely high on the job and hope you get the bid. What you are describing will take weeks to complete correctly. So, I would bid $4.00 a linear foot, and estimate high on the material, so say 5,000 linear feet (probably too much, but I'm not a plumber). Then I would add 25% for your vendor discount. So, I would bid $25,000. And that's just to replace the copper. You bid replacing drywall after the copper is in, and all the fixtures separately. Once again, my estimate may be high, but it's a starting point. Another suggestion is ask a plumber to give you an estimate.
