What would you charge for a 10 min meet only?
I once sat in a bar and watched a "speed dating" event. The same principle would be fun with relation to the hobby (impossible I know, but still fun).
The most interesting thing about it was talking to another guy at the bar as we watched. He made it a point to show up but never participate so he could score with the ladies who stayed at the bar afterwards, the guys who actually participated almost always left right after the meet up, alone.
I feel that too difficult to offer...10 minutes wouldn't be worth the gas, traffic, hassle, etc.
Dating sites are pretty good for those quick meetings, but a professional, legit provider will provide necessary information via the web from sites, membership validations like P411, ECCIE , and Date Check just to name a few- that way a 10 minute meet is not neccessary. Plus, Im sure a phone call of 10 minutes or more may suffice just as much papi...
