Hi my friend, I will help you do that.
1. I have ~100 ebay/amazon template (~20 adult template), which can support your item's detail professionally, such as themes, insert images/video, INSERT ITEMS WHICH YOUR ACCOUNT SELL (show images, price, and when customer click => they will move the item's post)
2. I have a realtime software base on data of ebay (I join in a group, each member pays 500$/year for using software). It show us a topten keywords for the tittle, top 5 categories (with exactly percentage) where the most seller listing item on, average price, Listing Types Breakdown (If you use Auction, I will give best time for your item to listing)
