FInish Magento supplier module

Hello, I need some Magento guru to finish a supplier module. A freelancer start his job but disappear:) The module is almost done. The main idea of the module: 1. Adding a new attribute - SUPPLIER - with details Company name , contact person , address, email , telephone 2 . Upon entry of goods to choose a supplier for the product ( attribute ) - default 3 . In admin when review an order for any product to be able to put the supply price of the product and vendor selection , if not the default vendor and date of purchase of the product. I prefer a new button SUPPLY PRICE, which open a new window with list of the products in order and field for vendor and price. 4. A New report which calculate the profit between supply price and sale price with possibility to select a period, status of orders and etc. 5 . From the admin orders list can be selected orders by status - for example New and pressing the button - Send Request to send letters to suppliers of each good. It must represent something like this: To Company XXXXXXXXX Request from {STORE_NAME}. Please give us your availability and pricing on the following items: Order Number Name of the product Options Count Status Price from Vendor 1000000001234 Item 1 Color red, Size S 2 1000000001245 Item 2 Color red 1 1000000003456 Item Size 3 38 3 1000000004566 Item 14 Color Black 1             Thank you {admin_name}              Orders that are sent inquiry to be marked in some way to not sending a new request or change their status . The module is working with [login to view URL] And in attached file is instruction for integration with this extension. The module now is on a test server and I will need to move files on my real server. You can see the module working here: front: [login to view URL] admin: [login to view URL] user: admin pass: admin123 Things to be finished: 1. Please add date/time in the field Email sent in orders grid. For example: Email sent 23-12-2014 20:14 2. If the product has custom option(s) or attribute(s) like this [login to view URL] in the suppliers mail this option(s) or attribute(s) must to be shown together with the SKU of the products on another field. It is important. 3. Possibility to change supplier in the order and then possibility to send a new mail to the new supplier. 4. Only one button Save in supplier price window. If you have any questions please contact me. Thank you
