After viewing the referenced site and attached PSD, i concluded that the site needs it's sizing adjusted dynamically, which will make it appear well on all devices including tabs.
I will adjust the CSS and JavaScript of the existing site without distorting or changing how it looks, of which the result will be that, the site displays well on any device used in accessing it.
I have over nine years experience deploying solutions like this and can guarantee you a very good job. Hope to hear from you soon. Thank you
