Alter the defauly links to better match the colour scheme of the site (which looks nice btw )

The enquiry form should not resize my browser

The header should preferably be text (better for SEO) but atleast you filled in the alt tag... which i've noticed a vast majority ignore...

Why not create the headers (both logo and in the content) as text as apposed to images? this is easier in the long run... and far better.
