All-in-one USB-C Dock for 2016 15" Macbook Pro
Sounds like you want a USB-C/Thunderbolt 3 dock. One cord connects all the peripherals you ask for to your Mac.

OWC makes several, StarTech makes several, Belkin makes amazing one - http://www.belkin.com/us/p/P-F4U095-APL/

Be sure you know if you're getting one that charges your Mac - they cost a little more, but should be much more stable for video / power and save your Apple adapter to sit in your go bag or the second place you plug in.

If you want a bargain - you could get a ThunderBolt 2 adapter, but then you still need a power cord and also the cost of TB-3 to TB-2 adapter. Probably not cheaper based on the prices I see today for docks.
