Java Marketplace Integrated into Website

Avg Bid (USD)
Project Budget (USD)
$2000 - $25000

Project Description:
I have a Joomla website with a database of product articles. I need someone to develop a custom java marketplace that will be integrated within the articles. So at the top of each article, someone can click Buy/Sell & will receive a java pop up marketplace that allows the user to post a "for sale" listing for that product or they can buy that product. It's a person 2 person marketplace. I need to charge a $1 listing to help cut down on spam. I assume the payment processing would be done through Paypal.
Ideally, if I was reading a "Canon T3i Camera" article I will be able to click "Buy" at the top of the page & will get a pop up with a list of "Canon T3i Camera's" in order of which are closest to me geographically. I could also click "Sell" at the top of that page & post my "Canon T3i Camera" for sale.
I have Joomla Jomsocial added to the website. So Ideally, the marketplace would attach the product listings to the Jomsocial user & could show a list of that sellers items & reviews.
Please don't respond unless you know Java & are familiar with Joomla. Please quote me the actual cost of this project, I have a budget for it & want to pay someone who is capable of finishing it, not the person that posted the lowest price.
Thanks for any interest in this project,
