The headphone jack is part of the Logic board (as you can see here). So replacing it is a big job (and costly).

I would first see if the jacks internal switch is twisted or dirty. Often one of the contacts spins around disabling the switch. Use a magnifier to look down into the hole to see if the contact is correct. Use a toothpick to move it over and/or clean the surface where the contacts touch.

If you can't fix it I would look at a USB adapter or stick with the Bluetooth headphones.
