develop a portfolio or brochure that shows some of your work as well as referral contacts from satisfied customers. Contact wedding planners to see if they would be willing to use and/or recommend your services. Drop off glossy flyers at florists that specialize in wedding arrangements... get a web page that not only showcases the work you've done, but also has testimonials from satisified customers. Join your local chamber of commerce and network.... be prepared to divulge your business information such as successes, failures, etc.

Nearly every large church has a wedding coordinator on staff (usually a volunteer)... make sure you get flyers and info out to them - many times a bride will trust their church coordinator to make these sort of recommendations.

Consider expanding to engagement photos as well... many bride-to-bes want pre-wedding photos to share with their friends... these are usually less formal than the actual wedding day photos.
