Amazon API Listing checker

Hi! We are looking to commission a script and database which will interface with the Amazon API We will upload the asin list on regular basis. Any new asins should be automatically added to the database. The script should run automatically/ regular intervals and pull the following from amazon for the asins list in database and update the database UPC Name Product Description Brand Product Features Amazon Image Link CATEGORY TITLE RANK Lowest New FBA Price TOTAL FBA OFFERS AMAZON PRICE (If amazon carries product) There should also be an option to schedule this for a specific asin list when required. The date and time of last update for each asin respectively should also be stored. There should also be an option to generate an excel or csv with certain criteria based on the above column (eg: generate list containing all above columns for a specific brand or list of brands or for specific category or list of categories, or price greater than, lower than, in between etc.) Also there should be an inbuilt check to insure that the api calls do not exceed the amazon mws call limits and proper safeguards are builtin.
