If you have a mailing list of customers who know you well, simply write a good letter and mail it. Nothing beats personal communication.
If you have a large mailing list of good customers, plus lots of prospects and lookers, hire a company (advertising agency, graphics house, direct mail firm, etc.) to design a post card or other type of mail piece.
If you don't have a mailing list of customers and prospects, you've been asleep at the wheel. Get a name and address of every contact you make. It's not hard.
In that case, if you don't have a list, search engine advertising is affordable and effective.
But nothing beats a mailing list of customers and prospects.
Good luck.
