Hello Andrew, and welcome to NSR-WORLD.
Your best bet here, it to post a wanted ad in the Classifieds section.
Other than that, really it's a case of keeping your eyes open on auction sites, and possibly places like MCN. MC21 prices are really starting to climb now, so it's getting harder to find reasonably priced "project bikes". A lot will depend on what kind of condition you want, but it seems the days of £1000 "fixer-uppers" are long gone!
