We need someone to input new products into our Magento e commerce website

We need someone to input our products onto our new 2 ecommerce website which are magento stores, so experience of magento would be useful.

This is to include product descriptions, images, review, keywords for search engines.

Experience of seo and marketing would be useful as we want to post all these products to google shopping and facebook store and all pages to be optimised for each product.

This is an on going project and we would like to cultivate a long term working relationship with the successful person to help us manage our ecommerce solutions.
