I'm moving to Kona next week and I'd be more than willing to heft a brew (or more!) with you.
HiAdv has a rental business in Kona, he has a thread in the vendors area. Look him up. There seems to be a strong Adv contingent on the Big Island, you shouldn't have any lack of suggestions.
Enjoy your time in Hawai'i, I'm sure you'll love it!
