The gear teeth make me think of mechanics or mechanical engineering, so if I saw only the image I'd think you were offering repair, or possibly design, services. And with the prop in the center I think "aircraft mechanic."
I like the color scheme. It's bold and drives the point. I also like the ones with a camera iris in the middle. To me that says "photography." (Or Aperture Labs of Half-Life fame.) I prefer the ones where the iris is the hub of the prop. That makes it smaller and less prominent but I feel like overlaying the prop on a larger iris makes it busy, and harder to recognize.
But I'm not a graphic designer, so treat everything I said as if it came from a drunk stranger at a bus stop.
