Moving nav menu position query


I’m trying to move the navbar navigation links and Get Started button on my website over to the right and right next to the phone number information but without pushing the Get Started button down. I’ve tried Flex but I seem to have to apply a massive left hand margin, and with float right it seems to push the Get Started button down.

Can anyone advise me the best way to do this please? Thank you. Share link below.
