Amazon Fulfillment (FBA) inventory + buybox inventory page

I need some software to help manage my [login to view URL] fulfillment inventory. This can either been done on a standard page with php/ajax/jquery OR google spreadsheets (offline mode) to parse a XML node I need the following things done in a table: - Item name - Item inventory left - Our current price (updates every 2 minutes with jquery/ajax whatever you want) - Current buybox price (item cost + shipping) (updates every 2 minutes with jquery/ajax whatever you want) - Item rank - Do we match the buybox price within 2% (updates every 2 minutes with jquery/ajax whatever you want) All of those can be updated with Amazon API I have about 2,000+ items in fulfillment, so this page is going to be resource heavy. I need you to take that into consideration. My budget its $100, I can negotiate if you're professional enough. Please do not spam your bid with a generic copy/paste offers. I want to speak to a real person.
