Why do you use "Scripts/jquery.jcarousel.js" and "Scripts/jquery.jcarousel.min.js"? The second one is minified version of the first one. You need one version, I preffer minified (the second). There are so many js files attached to your code, do you really need all of them?
You use CSS in external files, so why do you also use inline styles?
There is <link> with favicon before <head>!
Some of <link> tags are ended with "/>" the other are ended with ">". It should be more consistent.
There are a lot of <img> with empty "alt". I think some of them should be inserted into css as background-image (if they have decorative funtcion).
Generally your code is a little chaotic and complicated (to much divs, I think I may be designed with simpler code).
For some of users your website may be not functional because there are a lot of elements without outline and without :focus style. Sometimes I can't se which element has focus (I often use TAB key to go through "active elements" - links, buttons).
You are offering creating websites for others. I should expect something more from your website.
