HELP! Amazon Seller Central API Product Types XML

Hello, please post your estimate in number of hours and how long in total you think this would take you. Also, please share in your response how you have done similar work to this. If you do not have good experience with mws api and xml requirements, please do not respond. SHORT SUMMARY: 1) We either want someone to provide us with valid XML for each Amazon Product type that works on the mws API (i.e. you've already done this work and can just sell it to us) OR 2) We want an estimate on how many hours it would take for you to provide us with valid XML for each of the 300+ product types LONG VERSION: We are building a tool that lists products via Amazon seller central API (mws). When you list products you have to select a product type (i.e "shirt") The XLS template files for each product type that you can download from Seller Central include information that DOES NOT match what the API requires. Each product type has an XSD schema to validate it, but the XSD does not say which fields are required for each product type. For instance, "shirt" might have 4 required attributes (size, gender, material, etc) and 10 more optional attributes. We need XML for each product type which includes the required and optional fields for each one. There are 300+ different product types. We basically have been manually trying XML and waiting for Amazon API to respond with errors in order to troubleshoot which fields are missing. We are looking to have this completed asap. Thanks!
