It is important to have a logo / more distinctive branding on the site. I would also consider some UI updates. The color palette is one you should seek to improve, ideally through some A/B or multivariate testing. It is not clear (at least not at first glance) what conversion goals you are targeting, and what call to action you are hoping site visitors to take. It is very important to define those metrics before investing too much more time and effort on site enhancements and testing.
