Hori Ex-SE Repair?

Hey my fightstick recently crapped out. One of the buttons became stuck down and I heard some rattling around and opened the back (why not I was out of the 90 day warranty anyway) and saw a gold ball and spring lying there. The stick is a hori ex-se.

The rest of the stick works fine I just need the one button replaced. Does anyone know of a place/store (I am really leery of shipping my stick to a random person) that can repair this?

P.S. I live in the Philadelphia area if that helps. Also I am horrible at do it yourself jobs so I would like to avoid that!

Appreciate the answers in advance!

Also yes I did do a forum search and I did not see really anything that matched my problem.

You’ll get an answer if you post this in the Tech talk thread.
