Ensoniq ZR76 needing TLC ~5 keys (spring) SoundFinder knob loose

Hello I have an Ensoniq ZR76 with few keys (5) that are not lined up but still get sound when pressed (spring?) and the Sound/Rhythm Finder & Type knobs are loose
everything else works with no problem.
I live in Dallas TX. Let me know if you are able to fix and a timeline and I can bring this baby to you.
Thank you again
