AMAZON SELLER REPRICING TOOL

I need to create a repricing tool for my Amazon Seller Account 1) Should work for USA Amazon 2) I need to be able to enter my credentials through config user interface and have it saved in config file , including api and seller information - 3) system should automatically download my current product catalog including items that are Fulfilled By Amazon 4) I will download a csv that lists all my products and buy box owner name , buy box owner price and other featured seller name and price - I will then modify csv to set details on repricing for each ASIN , including minimum price, maximum price, 'beat buy' % or price , the system should then create new price feed and auto submit to amazon with new pricing. 5) I need to be able to set how often to reprice in config panel or csv , and would prefer to be able to set different items to update at different time interval. 6) need to have secure login site and admin control panel. I presume will be php and need some type of database. -developer needs to specify how much space and memory I need on server and suggest what type of hosting plan i need to handle ( VPS, Shared host, etc) -Devloper should either install on server, or have detailed instructions, including database setup. I am open to other suggestions for features
