Mate, with all due respect your site is not very good. It is very hard to follow and the different components on it are very disjoint - there is no flow.
For a start, if you are going to have that slideshow there, move it to the right hand side, I cant read your blurb on the right, because everytime the slide changes, my eye gets drawn back to the slide show.
That navigation in the middle does nothing for me. It is really hard to read, and in the wrong place.
Is there a reason why you have used Times New Roman for your heading?
There is no consistency in the font size on your pages either, some is smaller and some is bigger.
That gradient on the bottom renders really badly
And as said above, the site is waaaaaaaaay to wide.
This may sound rough, but I would honestly start over, in my opinion this site does not do your business any favours. You say on your homepage 'A sign is the representation of your business', so is a website and can you honestly say that this website honestly represents your business??
Do some research into what works well in a website - have a look around at other sites, there are plenty of good and bad ones out there - note what works well and what doesnt and then start again with yours.
Sorry, not trying to bag you at all - just being honest with my 2 cents.
Hope that helps
Rob
