ecrater.com seems just to be a free e-commerce site and I doubt they'll allow you to put your own affiliate ads on there and then you'd need some actual products to sell, obviously if you run a shopping site already it shouldn't be problem. If you're looking for a totally affiliate orientated site your probably better looking to create a BANS site, easiest to start with is amazon astores or ebays partner network, search on here and you'll find lots about them.
I have products to sell, but the site will only some access. I don't think I will be able to put any links on the site. I only have access to the meta description tag, and meta keywords and uploading pictures and descriptions of products.
