Importing and processing products from an e-commerce store to E-Bay Webstore

I have a complete professional apparel store and I just opened a new webstore at E-bay, what I want to do is to import my full product catalog (about 1400 products) from an excel datasheet (provided by me) to a new E-bay webstore, that includes converting the excel sheet from my actual store to the E-bay Store import template with all the sizes and colors. The job is very simple and I will provide you with the E-bay webstore template and all the information you need from my actual store. The E-bay webstore has to be fully functional and no broken links, or missing any details. The action of importing has to be done by you, the E-bay webstore has to be fully functional.
