Brother Jeff,
If you are on the level , You might take to placing those square pieces of paper under windshield wipers until you are plumb tuckered out!
Seriously though, fliering heavily would be a low-cost way to guage interest in the area. It's been awhile since I have been to Columbus and I don't know the location of the building off the top of my head. If you would be close to thos shopping malls, like the one where Dick Clark's restuarant is, those would be good places to start.
With respect,
Mitch Saret
