Design Your Own Ring Web App

I need a “Design Your Own Ring Web” web application built. It needs to be similar to Zales – Design your own ring application.

Please provide example of similar work.

Here is a link to the Competitors application: http://engagementring.theprestigediamondcollection.com/EngagementRing/ERing.aspx

It may need to be written in php. Not sure.
