I like most of it. I also think that the buttons are maybe a bit too big, but that easilly fixable. Also, you should preload the orange mouseover image, as it takes too long to "change" the first time.
The logo is the main problem for me. It takes up too much space and is too plain. Either make it smaller, and therefore more discrete, or keep it the same size, but make it more graphical and better to look at!
First of all I really liked the colors for your website, but. I really don't liked what happend in here:
You will need to fix that, because it really pisses people off. And about the originality, there are LOTS of web design websites which has services like that and they are much better. I'm not saying this to piss you off and close your site, I'm saying this so that you'll fix and add things to you website to help build up the potential for your website.
