Will you have to place a large bulk order on your brochures or will you be able to print them off as needed (or order in small batches)?
Smaller batches allow you to tweak your product descriptions/prices as needed. If you are going to place a high volume order for an expensive, slick paper, multicolor brochure you might consider a separate brochure "insert" with your pricing. This insert could be colored card stock xeroxed down at Kinko's...three inserts to the sheet.
Sometimes factors beyond your control can add to your advertising expense...about 20 years ago GTE decided to assign a new prefix to the phone numbers in the central part of our state...I had to scrap business cards, letterhead, magnetic door signs and so on. It probably didn't cost me more than $500 but it still was a bite!
