Integration for editable advertisement artwork templates?

Hey all,

I'm wondering if anyone has a solution for this:

We're looking to host editable marketing/ad templates on a team site so that local retail branches could customize information in the layout (their branch address, phone, etc.) and then save the ad artwork out to publish in a local paper, via digital, etc. Can anyone think of a way to facilitate this?

If every branch manager had access to Adobe Acrobat Pro, then it could be a PDF of the ad artwork with a form field overlaid, but unfortunately that's not the case. Any help is appreciated!
