i agree with harry. if you're worried about high quality tools being ruined, shelve them for a while, buy a set of harbor freight lathe tools, a grinder and learn yourself. a misconception i had when i started was that you can't turn with a tool that isn't sharpened EXACTLY as it's supposed to be. i was wrong. provided, i'm sure i'm not getting the best cut possible, but it's nice see your learning advance. i definitely notice a difference now from when i was first sharpening them myself (and it's only been a shade over a month). not only in the form of a smooth bevel, but the shavings are improving.
the harbor freight set is only about $45 and therefore worth the investment in skill learned. 8 tools also.
or if you don't want to bother, you could take them to a local woodturning meeting and i'm sure someone there would be willing to help you out.
