Integrate Facebook, eBay and Amazon Stores with a Zencart based eCommerce website.

Hello, We have a online store which is made in Zencart, and we need to integrate this with our facebook, eBay and Amazon stores. What it should do is given below: 1. When we upload products in our Zencart store it should be automatically uploaded to facebook, eBay and Amazon stores. 2. When we modify the products in our zencart store, it should be modified at all places automatically. (If Possible) 3. When we delete some product from our zencart store, it should be deleted from all stores- facebook, eBay and Amazon stores. (If possible). 4. Bulk uploading through CSV is also required. That means if we upload a CSV with 2000 products in our Zencart store, it should be uploaded to all the stores, facebook, eBay and Amazon stores of our company. 5. This is not a requirement, just to confirm that you read the entire description properly, please mention "I am Human" as first line of your proposal. Proposals without this line will be straight away rejected. This project is a great opportunity for a person, or team, to be in a long term relationship with us, as we are likely to have similar projects in near future, that is for integration of stores with marketplaces. So, this will be a long term relationship. Only person or team that has done something like this before should apply. Please do not bid blindly, read the description very well first. No time wasters please. Happy Bidding..!! Thanks Varun
