Back when the sadly missed Rod Gibson was editor of classic motorcycle mechanics magazine, he published Paul Jacksons details without beong paid for an advert because he reaconed Paul was the only one doing the job, though you might find an adventurous engineer willing to take it on. I've done a few for myself but wouldn't even try to compete with Paul Jacksons rate, takes too long with my little lathe. I'm sure it would be fine to post the wheel.
