Marketing Designs

We are currently working on putting a small design catalog together to take to various schools and booster clubs over the summer. My question is how do you'll deal with marketing designs? By that I mean if a groups selects a certain design for their organization and another group say in the next town (10 miles away) wants to use the same design what do you do? My personal thought is that if one group has already picked and committed to a design it is off the table and the other group needs to pick another design.

I would appreciate any thoughts on this.

Thanks
Larry
