Hi,
I have developed software for over 20 years, and have lots of experience with most web-related technologies, both server-side and client-side, including HTML, CSS, Javascript, jQuery, php, etc.
Can you share the address of the site and give specific details of what should be changed? If it's just a matter of repositioning a menu it should be a quick fix.
Let me know if you can provide the above details or have any questions.
Jacques.
