I have e-bay store and need to do some configuration and set up some product, some is upload already some i need to upload, total of 30 products (woman clothing) in 2 category, need to set proper each product, I will provide the info, only for BUY NOW so it will be no fee from e-bay per item. I will need instruction how to do it for later. I will need set up for size to ( woman clothing large, extra large..... in each item) I have all ready 10 items that was in action and in the account so I need to add some more and set up all proper as I need. I will choose the best price coder; this is a simple project for the person that knowe bay store. Thank you
