Well I thought of this great idea.
I don't mind sharing it with you all...
I bought some postcards from office max (4 postcards per page)
I put my info at the top then gave a choice of Full billing service or collection service (they would have to check either or)
Then I gave three more options
briefly stating as [of course the ones on the card do not say blah blah blah, it's just an example
]
opt 1: We are interested blah blah blah
Contact Name
Specialty
Best contact time
opt 2: keep us on mailing list, thinking about it.
opt 3: we are happy with current services
Then I bought a book of stamps, printed my return address on the response envelopes, place a stamp (since statistically if a person/company sees a pd stamp, they'll respond) then I sent some other brief info I came up with.
All in all, being creative. That was my Advertisement #1 Option. I've come up with about 6 different others. Hope this could be some help for you all.
