Going price will be dictated by your area. Commercial vinyl is priced by the linear yard. Lin yd is determined by the surface square feet, divided by 12. This figure will give you a small overage percentage for waste and defects. Price to install vinyl runs anywhere from $4 lin yd to $10-12 range for high end and small jobs with $6-8 being average. Adhesive might be included in this price, or might not. Find out from the GC if he is providing the paste, or if the hanger needs to. Again, this will be dictated by your area. Find a good hanger in your area, and ask them what they charge to hang commercial vinyl. Add a couple bucks on to that, and submit the price. But your best bet is to find a good hanger in your area, and explain your situation. He or she can guide you along in the process. If you need a recommendation for a local hanger, let me know and I can usually find one.
Remember, if its a big job, you could lose a lot of $$$ if not a very good or fast installer. And also be aware if someone is asking you to install over old vinyl, this is against the firecode in may many major cities.
BTW, it's called
priming. No one sizes anymore.
