Fixing XM4s?

So I've run into the common issue of a damaged hinge swivel and it makes my headphones impossible to fully place on my head and embarrassing to wear in public.

I honestly don't trust myself to fix it myself even if I ordered the part. Is there anywhere I could fix this problem for less than 120 USD? Is there shops that fix this issue or am I out of luck here? The big problem is that the warranty wore off a while ago and I have the best buy exclusive midnight blues so getting a full ear replacement probably would be difficult so if I could only get the hinge fixed that's preferable.
