Web Hosting Ideas/Comments/Suggestions

Hello,

I am developing our new online presence, and I am attempting to create a sleek simple presence, but with hosting a lot of information needs to be accessible by clients and displayed at once, so they can find what they need fast and simple.

Here is my current site, and I am slightly disappointed with how its turning out.

Any suggestions or comments or ideas on how I can make this more sleek and professional?

Thanks!
