Content window popup in existing joomla 2.5 website

PLEASE NOTE THIS PROJECT IS ONLY FOR A POPUP WINDOW, NOT ENTIRE WEBSITE. I need an expert to develop a popup window in existing joomla site. Please see this example, [login to view URL] Scroll down the page to the area with product image. There you can see " + " in circles and on rollover there is a popup window. Hope that makes any sense =) Well this is the effect I need. I need to be able to display article content in small rollover windows on my website. Attached are images. All pages are ready. I need an expert, and the project needs to be done quickly, so please consider that when placing a bid. thank you!
