I think that there is too much happening on the front. I suggest trying to say more with a lot fewer words. Most people are not going to read all of that, even if it would only take them a few seconds. They just won't.
Try for a simple, bold headline and a couple of bullet points, nothing more. Your flyer needs to get their attention, not tell them everything. After you have their attention, then you give them all of the details yourself, in person.
A graphic design principle is that open space is your friend. Don't try to use every square inch of the flyer. Chris is right about the drop shadows. I would consider getting rid of the "Free Estimates" medallion. Free estimates are assumed. Less is more.
