Design an Upselling Layer according to our CD (PSD)

I need a PSD for a new design for an upselling layer on our site. I can provide basic PSDs with our current design, so you can use that for the layer design. It is important to me that the new design is made according to the design we already use for our onlineshop. Colors and buttons should match the existing ones. Fonts and text styles should be the same. I will give you access to our live site, so you can look into our design and existing layer desings on your own. I need this project done asap, maximum deadline are 2 days.
