USB-C to HDMI and VGA adapter for MacBook Pro 2017 touch bar

I'm looking for a multi-port adapter that will allow me to carry around a single dongle when giving presentations with my MacBook, as some classrooms only have VGA or HDMI. I purchased one for ~$35 online, only to find out that it doesn't work with the new 2017 touch bar models, which I have. There was one on Amazon that I found (made by Aukey) for ~$70 that was said to work with my model, but now it's sold out and I can't find one anywhere. Any help would be appreciated!
