You're a photography service but if I don't take the time to read all your text I might just think you are just selling photos since there are a lot of sites that do just that.
While your content covers the messages you want to say, it is edge to edge text with no bullets or change in type style to emphasize any particular points. The dark blue background with orange text also discourages one from wanting to read all that text. Since you are providing a service you can easily show examples of, you should. The photo gallery you have is not of pictures of the type you are offering.
I would classify your site as a brochure site, not a sales pitch site so it is not motivating a instant buy. Of the 113, many probably came to your site as a result of your flyers but may not have been in the market for a photographer at the time.
If you follow some the suggestions made here by the other posters and keep working at improving your site and maybe your flyer as well, you will eventually start to see results. Hang in there, work at it.
