UNLEASHED Integration. Order collection and tracking feedback

I have a client that is potentially going to be using UNLEASED as their stock management portal. I need a developer that can work their way through the following: [login to view URL] Part 1: The first part is to return the follwing data: 1) Sales Orders: Order Number, SKUs, Quantity per SKU, Status 2) Sales Order Address: Order Number, Address, ZIP/PostCode, Country, Consignment Weight This will be for a period of x days, depending on what is available. This will be in an XML form, or something that I can use in PHP so that I can basically, to drop the above two parts into a database. Part 2: Is to create the feedback code, that allows me to send back confirmation of picking, a tracking number, carrier name and the order number for each order. This can be done in batches ideally. Please let me know if you can do this.
