You need to include an offer, front and center. A coupon or something. It should be hard to resist. This is the most important thing you can do with this site. Design issues are secondary to whether you have an ir-resistable offer.

Your landing page doesn't tell the viewer anything about the business, what benefits do you offer, and especially, WHY should I click to go to the next page?
