By the way, the homepage is bit of a mess on Safari + Mac (I know you're not asking for that kind of feedback but yeh...).

Side-scrolling main frame thing is just awkward. Some of the images overlap as well.

I don't think this is something that people will know they need, or at least, not know what to call. So approaching potential customers through forums, reviews on relevant blogs, widgets/partnerships sounds like a reasonable route to take.
