Ecommerce System - Website - eBay Store editor/manager

We require a ecommerce system manager to operate, manage, make changes etc to our current system. We are using the NETO ecommerce system which integrates our website and ebay store together for sales and stock control etc. We are at a stage where we need to re develop our set up and create new categories etc for our website and eBay store, this will involve SEO work, category mapping on Neto to suit eBay sales categories and general maintenance and running of our Neto system. We are also about to introduce another 1 or 2 ebay stores to separate some of our products to make online shopping easier for our customers. This will involve new areas of development in sebat store designs, mapping and also sort orders for all of our products. We have a wide range of products and approx 900 items online at present but expect this to grow to 1100 in the coming months. We would like a time flexible freelancer that can commit to a reasonable number of hours per week at first and once we get system updated we would prefer our freelancer to be available for ongoing work in regards to site/system maintenance etc. Knowledge of the Neto ecommerce system would be an advantage but not essential as long as freelancer is a quick learner and very competent in regards to accuracy and checks to ensure all systems are in full working order and showing correct and relevant information. In summary: Competent and Loyal. Trustworthy and willing to sign privacy agreements. Very cable with websites, ebay store and ebay's systems, good knowledge of ecommerce systems like Neto. Excellent knowledge of eBay sales categories and where different website categories are mapped to on eBay through the Neto category mapping system. Thorough and accountable to quality of work provided. Open to suggestions and instructions from employer. Ability to recommend and inform management on improvements to our systems in use. SEO optimisation to ensure a high search engine rankings. We currently have the Neto system up and running with website and eBay store, however after 2 years we are now in need of a major revamp in categories and linking with eBay as many areas here are now not syncing due to changes.
