Hi Sir, i read and undersatand your job decription clearly and i am welling to start listing your products at eBay as soon as possible. I have a very similar experiences regarding product entry fro the clients in EZhopz, Bigcommerce and Opencart. All of this online shops are almost thesame by the way you create and update products and there are only little difference. Ebay is not that different from all of this shops and I can do your task of 500 products with in 7-10 days for only $88. I just only need your log in info and pecifics on how would you want your products to look like on abay. I hope that you will accept my bid in this project. I will be waiting for your positive response, thank you.
Hoping,
John
