Got your faxes, they hide very well. This is all I found:

associated with 800-778-4179
and I called 800-821-6601 she answered "reservations" I asked for some off the wall name, Brooks mfg. she said it was USA Vacation in Florida.
You might want to call that # and ask who does their ad campaign through faxes (like the one you got for them) and play them like you want to hire this company to do your ad campaign. That might be the only way to find em, but if we can find who they are, then ya got em.
what information comes across the top of the fax, (it's probably phony, but what does it say on like a few of em) All I got was your information, from your fax machine/company.
