In a previous life, I ran a small independent record label. I used to do co-op ad buys with my distributors all the time. Some times they worked, sometimes I just hoped I got a little bit of exposure. The key is consistent high quality work. Someone needs to be the yes/no guy/gal. And people need to deal with it. The key is to do it issue after issue, and have it professionally designed and consistent. I too would be interested if selected, and have a few designers at work that I could tap for the design work. Let me know. Oh yeah, I think it would have to be full page if not a two page spread. Pricey, but it would have impact.
