Rather than spending several thousand dollars on this project, the headaches of bottling and importing it, and possibly ending up with a cask that is less than the quality you hoped for, I'd probably just buy some cases of scotch from his birth year. You don't want 18 yr old bottles now, you want them 17 years from now. You can pick up a case of several different scotches along the way. Ie 10 yr, 12, 15, 18, etc. Some, like Glenrothes, offer vintages by year.
I would really not want 200+ bottles of the same scotch. What would I do with them? A few for a blow out party, 50 bottles for me in storage, than what? 150+ gifts? Maybe he won't even like it. You could give them away as party gifts, but the recipients would likely not appreciate what they were, or the time and $ that went into the project.
