Looking for help repairing(re-soldering) two switches on a vintage Zenith ZKB-2

I have a modified Zenith ZKB-2. It has green Alps. Two keys, caps locks and the lower right Shift key, are not working. I need help repairing those two switched. I believe they just need re-soldering. I would pay for the servicing. I am in the Detroit area and could ship the board to you. Thanks.
