Where are you located and is the boat fiberglass or aluminum ? Most of the poly jobs that size i do come in under 2k and using good quality uhmw poly, (also depends on if you want all your holes welded if alum hull or so on) also you can buy whatever poly you want and we can install riveted or screwed to your preference, im not trying to get your job just call around on quotes and get references a bad poly job can ruin your ride if not done right so take it to someone good, on the other hand if you want to tackle it on your own well thats fine too its a job but with the proper insight and help im sure most can do it , i encourage folks to do a lot of there own work if your confident in your abilities , there's nothing more gratifying than a job well done by your own hands , give us a hollar or shoot me a txt email whatever works if you need a hand or advice thanks
