Help with repairing broken titanium glasses

Hey all, I have some prescription sunglasses with a titanium frame my son managed to snap in two at the nose. Titanium is pretty nasty to solder so I’ve had no luck with that, but a skilled TIG welder should be able to tack it together pretty easily. Unfortunately I’m not a skilled TIG welder so I need some help with that. I’ve attached a picture of what the damage looks like, and am willing to toss a twenty at it if someone thinks it’s a quick and easy fix for them. Thanks.
