You go get a newspaper route and be nice to the old ladies chalking up mundane conversations about houseplants or chihuahuas for extra tips until you've saved up about 150 bucks. Then you abruptly abandon your post, leaving the old ladies wondering what happened to the polite young man with all the zits, take the board to a shaper who does ding repair, and drop it off for about a week.
Seriously though this would require buying 4 oz. glass and I'm guessing epoxy resin, though the price is pretty much the same for poly (expensive!) and going through a pretty tricky process, especially if you've never glassed a whole board, which is actually easier than fixing this little gem.
