Configure the module for Premium Business Directory listing in Drupal 7.20

This portal - [login to view URL] is in development phase being developed in 7.20. I need a premium business directory listing module in this portal where users can make paid listings in business directory. The flow goes like this - User comes, selects a listing option (may be 2-3 paid plans), creates a new node, make payments(ccavenue), node goes to admin for approval, admin approves, node is published in business listing area. The add/edit options for his node should also be there in users dashboard. Any User - authenticated or guest can create this node. If guest creates this node, his account should be created in this process. you can use pay-per-node, commerce node checkout or any other module as per your convenience. I expect the delivery time to be 2-3 days. This is just a sample project. There is a lot more to come. I am looking for long term associations. When you bid, please provide portfolio for Drupal only. Thanks
