"Walls" String/Cello Cover

I know this is a long shot, but I figured it couldn't hurt to ask!

I'm trying to help a bride who is getting married in a little under a month. She's a big fan of Tom Petty, and has been trying to locate a version of "Walls" that would be appropriate to walk down the aisle to, ideally something like a string quartet or cello cover. I didn't think that it would be hard to find, but surprisingly it's been remarkably difficult! So, I'm coming to reddit for help in the hopes that maybe some of you have come across something similar to this before and could help point me in the right direction.

Any help is appreciated, thanks a lot everyone!
