Amazon Multi-Variation listing in the Electronic Category with xml, xsd

We need somebody who has experience listing multi-variation listings on Amazon US, with XML for the Consumer Electronics category with an XSD file. We need somebody who has done this before. The listings will be in the consumer electronics accessories category which is not a typical multi-variation option with Amazon. Amazon has advised that we need the items listed below: We need the following created: 1) A parent item, add all the relevant information to it, such as the name, description, pullet points, and most importantly the variation theme 2) The variation theme will define the relationship between the children items. If you are selling items in different size you will have to define a size variation. 3) In addition to creating a parent you will have to assign the variation theme to the children and the variation attribute. We have 1 listing to be completed currently and if this is successful we will have 30-50 listings that need variations in the next few weeks. We only want to work with somebody who has experience with this and would like examples of your previous completed projects. We want to build an ongoing relationship as we are going to be expanding our inventory within the next few months. We need everything up and working and in order before payment. Please only enquire if you have first hand experience with this and examples. We need a professional. We need this project completed as soon as possible. Please let me know if you have any questions regarding this. Thanks
