Auto-Price Management for Amazon Seller Central account

For the Amazon Seller Central account ([login to view URL]) , I need to have a script to auto-adjust pricing for each item that I sell within the acocunt. Here are the requirements: 1. I can set how frequent this script can run (e.g. once a day, every 1 hour and etc) 2. The script will read a csv file. The csv file will contain the "lowest price that I am willing to sell" for each item. 3. I can set some parameters to determine how aggresive that I want to do my pricing against my competitors. e.g. I will sell x% lower or higher than the lowest price competitor. 4. The script can find out if my listing and my competitor listing is a FBA listing or not. The pricing logic will act differently according to this factor. 5. The script will generate a log file to show the result of each run. e.g. show old price and the new adjusted price. Please reply with your experience with Amazon Seller Central programming and your price for this project. Thanks
