I've started several businesses and get bombarded with offers from ad-agencies, CPA's, attorneys, etc... who constantly monitor new businesses popping up. I throw most everything away. The con being that you will be one of many companies contacting the new businesses. I would suggest getting ahold of new business directories (perhaps in your local paper) that way you can target them specifically and screen who you contact.

Just my two cents!
