Perrealo Store

I have an OScommerce store which has already been installed, all I need is a designed template to match that of the main site. [login to view URL] is the main site and the store is installed at [login to view URL] I need this store to match design and color with the main one and include some flash and nice graphics which should also be included. I am looking to buy a template but would like to see what the cost would be for someone to do it for me. I am not looking to spend a lot of money due to some very nice templates being sold already so if your interested make sure the price is good and competitive with the templates offered. My budget isnt very high but I do pay promptly. I also need this to be connected to my Mambo site so users dont have to re-register when they want to make a purchase. Mambo/Joomla has a component to do this so I know it isnt hard, the component would just need to be installed. Thank You
