Ebay Amazon shop front and listing management

hi, i have currently a site in development. which is almost ready for live but needs touch ups. i have listed the project if you are interested to work on it or do it as a whole project. [login to view URL] is my website. i have have shop in ebay 'bradfordthread' i need to have the shop front done and the listing customised for ease. i have customers from all other the world and most importantly it needs to be mobile phone friendly. you can view my current listings on ebay and i need to have the simple 'weight, composition, shade, pattern, namedge etc' to stand out as that is what my clients look at once they see the images. i have produced inventory/financial model in excel so not sure if that can be linked. i will have more of the similiar products so i want it easily uploaded and managed too. i have a website created in wordpress so i am not sure if its needs to be linked. also i sell by the meters and ship worldwide. i have contract with shipping couriers so would need to apply that also in the ebay listings. i have not touched amazon as i am not sure how amazon works and if you are able to set me up, i will take you up on that offer.
