I watched your site in different browsers
2. in custom price offer now I added link of contact page "it seems the link is not there"
as contact is also down under the page and in the navigation bar it is a minor thing.

Do you know the developers tools in firefox , chrome, explorer they can be very handy.
During the lessons I took we had to use them frequently

also the w3schools validation can be very handy
