Using targeted mailers to help rent a medical office

I have a medical office that I am working on leasing out. Part of my strategy is to do a mailer to other medical practices in a 10 mile radius (around 100).

Has anyone had success with a mailer like this? Any tips on what to send (postcard vs. 8.5x11 ad)? What to offer (free month, etc.)?

Thanks!

A better use of your time would be to hit practices in the next submarket over or on a hospital campus to find someone who wants a second location.
