hi
i don't actually mind the colour scheme on here but i don't like the texture effect - when i landed on your site it looks like it should be selling kitchens or wooden floors. block colours look simpler, cleaner and more modern. also perhaps you could use another colour to lift the browns a little (see gotomedia.com who have a lovely colour scheme IMO)
the navigation is clear and easy to use but personally i would get rid of the IE default bright blue for rollovers used in the content - why style your site so nicely and have a colour scheme if you are going to use this gaudy blue colour?
Also i would not have any text centre aligned as it is difficult to read (promotions and forum section)
i'm no
seo expert but i would agree you need a lot more content.
you should also have a "call-to-action" on the home page as well as the main navigation - you have 4 large images and no click throughs - why not make the 3 right hand images thumbnails of your most recent clients? and have a click through to a latest offer or new offering on the large picture? encourages people to click through more.
hope this helps :-)
