My first recommendation would be to remove the rigging, package it up and drive/ship it to SNer Knothead, have them remade properly and then reinstall them yourself.
My second would be to do the same with any other reputable local rigger. You don't need to pay a pro $100/hr to remove cotter pins and unscrew turnbuckles. Even removing the mast can be DIY except for the hoist/crane but that depends on your comfort level and the facilities at hand. If you do tackle this yourself be sure to remember any internal wiring connections (often hidden).
Another recommendation I've heard is to have the rigging fabricated with swaged upper terminals, and do the lower deck level terminals with norseman or stayloc style... I've never used them but didn't think special tools were required?
