I think it's just that your audience is very specific -- i.e., people looking for a wedding/event photographer. Are you visiting other wedding- & event-specific blogs and getting to know people there? Since your blog is less a photoblog (or "me-me-me" blog, lol) and more an opportunity to promote your work, maybe those are the places to build the types of relationships you need.
Your "About" page says some very nice things, so you might want to include some of what you've written there on your home page -- just a line or two so visitors get a sense of what you're about as soon as they arrive.
My two cents.
