Have a search on the net for Joomla.
ive made both the websites for both sides of my job and with easy.
It may not be suitable for what u need as its an open source Content management system, but is really easy to use, dont need to no how to code, thousand of themes (u can get free ones or premium ones)
if you are fairly competent on the comp and hav acess to a program like photoshop of paintshop pro, once you have the theme u like its fairly simple to find the images files for the theme then u can changes colours etc (both my sites are the same themes, i just changed the colours via the image files)

let me know if this helps or want more info, and i shall help anyway i can
