Are hulls that hard to come by where you live?
Here in west florida, good solid PWC hulls are tossed out all the time. Heck, I have a complete Seadoo that ran great last time I had it out (2 years ago), perfect hull, was running motor, 100% complete, includes trailer, that I would love to unload for $200. Weather and sitting now has it looking rough. No takers so far after 18 months. I know couple people with perfect spare hulls that might pay you to get them out of their yards.
Edit: here is what a typical $400 (when I bought it) runs great PWC w/trailer looks like:
