gsonline is right, you are wasting so much space. it is looking dull. People not going to pay you cause your site looks in pity condition. I suggest google search free website template and then choose from them. It is very easy to edit. If you face any difficulty in editing you can ask me. I can't help you in coding but help you in transforming its look so that no body can figure out that it is a free template.
I have used one free template. You can visit my website. This site is based on helping poor and orphan children in India. It is not yet complete and my English is also so poor but you can see it.

By the way if we can work together then it will be very nice. The site will grow more and so more traffic and more clients for you and more ad click so more dollars for me.
