I see that you're going for almost a one page website but that is too much content for only one page. If you decide to add more pages, the menu bar with "Home" and "Content" should be placed at the top with the logo. A different color could be chosen as black just does fit well with your chosen colors.
Your most important contact information like your phone number or email can stay at the top but everything else should be in the contact page.
Lastly, you're right in feeling that it's cluttered. To remove the clutter, move content to other pages and then add negative space!

Okay so I should have visited the website before writing a review. It should have been obvious to me that the four boxes linking to each of your service were also navigational elements. I also noticed that you have a summary for each of your services. I think this a little redundant so I think you should just remove the top most service boxes and keep the summarized portions.
