Whenever I've talked to him he's usually been juggling 3 or 4 things at the same time and often comes off as being distant. I really believe it's just because he has that much going on, and that's his personality. I would shoot him an email to see if it's something he might be interested in or if it would be an imposition, with a phone # he could call you at if he would prefer to talk rather than type. The nice thing about email is that you can deal with it in spare moments of your choosing, while a phone call or visit brings whatever your doing to a screeching halt. If you come up empty, email me at the shop and I'll ask Jim across the street who the guy is in Chicago that he has used.
