Hey,
I think your site is has some really vibrant colours, and definantly appeals to the user.
One think I would suggest is using a container or a wrapper so that your content looks the same in every browser resolution.
If you want to add more pages, you will need a navigation bar which I would suggest you put on the left hand side, or just below the title/header.
If you want your site to look that little more professional try adding capital letters before each bullet point and test out different colours to really emphasize your services to your visitors!
Great site.
