Any suggestions for marketing the advertising product at
www.creativemailers.com. I'm on a tight budget.

Just a comment Jim,

Assuming you want to sell those specialty mailers, I would start
locally, taking samples in a portfolio, and cases in the trunk of my
car.  I would go to all the "pony express" type stores, and printing
companies first, then any store that sells envelopes and small
shipping boxes. Later, after I got it going, I'd begin pitching the
bigger chains like "Office Max" "Office Depot."  Those accounts take
longer, and you must be polished to gain the trust of the buyer.
