I do like the logo; it's professional-looking. I also like the blend of colors, it's rather pleasing to the eyes, IMO; not too much blue, and not an eye-hurting shade of blue.
Like what everyone else said, there is nothing on the site to really catch and keep anyone's attention. You want to get their attention, keep their attention, and get them to act (buy your services). Your site does not do any of these things.
There isn't any content by which to judge your site:
You have nothing in your portfolio section. If you actually have no sites to put there then I suggest you create some to show visitors the diverseness of your skill.
The most critical thing you're missing is a services section. A lot of web design companies will list the types of services they offer so visitors viewing the site can review the services to see if they offer what they want. I have no idea from looking at your site what you really offer besides basic HTML and a CMS. Do you offer Flash, graphic/logo design, shopping carts, database development/design? Do you develop in any languages besides PHP or do custom application development?
If you have an actual physical address and phone number for your site then listing them on your site will legitimize it more than just having a web address. When I look at web design sites, trustworthiness is based in part on whether they have an actual physical address and/or telephone number by which to contact them. Of course it's not required, and some companies don't have these things, but it can, IMO, increase the trustworthiness of your site.
If you want some ideas, or to benchmark your site against some of the better ones (subjective, yes) then take a look in these categories, some sites are excellent and obviously done by professionals, and some are not, but you can maybe get some ideas for your own site. http://www.dmoz.org/Computers/Internet/Web_Design_and_Development/Designers/
I know your site is incomplete, so I expect more information will be added to it over time.
