The best single-supply 3/5v rail-to-rail auto-zero
geoophone op-amp that I have found is the ada4528-1

It even gives great <0.1hz performance even at 10,000x gain.

Unfortunately it is only available in surface mount.  I have some
DIP8 carrier boards that I use to convert surface mount to DIP

I can provide an ada4528-1 on a DIP8 adapter for $10 plus shipping.
