Personally I think it needs some colour/imagery on there. At the minute it comes across as quite cold an unwelcoming, and appears to be unfinished/a basic wireframe. I'd beef up the headings too, making them a larger size and/or heavier weight.
The site of the agency that designed/built yours appears to also be unfinished. I'd hazard a guess that you're one of, if not the, first clients?
it seems there's nowhere to go in the site. It'd be great to really screw down through the site to find out about your products, processes, clients, business ethos,... but it just seems to stop, where you'd hope it was about to give you an incite into the business.
