Write some Software -- 2

Hi, I've developed a Wordpress Marketplace thanks to using a 3rd party theme and plugins. I have a few bugs that need to fixed such as: Login Redirect Show username upon login Align widgets And, I also need someone to develop a communication tool to be implemented once a transaction happens. This tool would consist of 2 buttons. 1 that says "Confirm Order" which the seller needs to click on after a buyer purchases their product. This would then Auto generate an email to the Buyer. A second button that if clicked, would be for when an order has been finished being made. The seller clicks this button and it auto generates an email to the site admin with the Purchase Details, Buyer info (Name, drop off address), and Seller Details (Name, address, pick up address).
