Estimate the time doing the job yourself, and multiply by three (3) !
If you are a DIYer, you can readily learn to do the work. If you are in a hurry to get the boat done and in use, forget it.
If you do it yorself having the time, the cost savings can be 80-90 percent since it' s mostly labor, vs hiring it out.
I expect you will be getting the boat for pennies, so if you find along the way it's time to throw in the towel, no big deal. Call the junk yard to haul it away!
To work with glass outdoor, you need seasonal temps, or otherwise indoor can work year round.
