Magento Extensions

Hi, I need 2 extensions for my Magento site. 1. Purchase Order Generator: Need an automatic generator to create a list of products need to be purchased from supplier. The program will check within new sales orders to see if any product within these orders is out of stock then generate a PDF or Word purchase order with my company info, supplier info, purchase date, expect delivery date, list of products, product quantities, each product cost, total cost etc... 2. 2 Way Messaging System within Magento: An in-store messaging function like this one [login to view URL] A section where customer can receive admin messages. Admin can choose to send individual message or group message.
