Getting my services out there...?

I do calligraphy on the side and would like to start doing it more often…kind of like a small business (but “independent”…if you know what I mean). I want to introduce myself to local wedding coordinators, invitation distributers, etc. What would be the best approach? I’ve written an email I was going to forward to theses local businesses. Is it expected of me to say I will give them a percentage of what I receive? My services are extremely inexpensive compared to most calligraphers, so I don’t make a huge profit for each job, so I would like to avoid splitting commission. I’ve worked with one of the top local wedding coordinators from time to time over the past 3 years and she has never asked me for anything in return, so I’ve been lucky there. What’s the best way to go? I’ve but together sample packages and business cards to distribute to the businesses if they set up a meeting with me…figured that was one step in the right direction.
