You can ship via fedex but it's much more expensive than USPS. To ensure tracking all the way select USPS Express mail international. How much it'll cost will depend on the weight of the package, of course. Get a box big enough to comfortably fit both. And yes, you can and should ask for more than what you charge for CONUS shipping. Send him a combined invoice with the updated shipping charges after you've weighed the box.
