Change the feed capacitor to 330nf and the other one to 15uf.

If you run a bode plot this amplifier shows attention up to about 1K Hz.

Yet you set (maybe by mistake? ) The input frequency at 60 Hz??? At this frequency the bypass capacitor is currently cutting out frequencies as low as this.

If you want an amplifier of this design to function properly down to 60 Hz, no problem! Just increase the bypass capacitance to 1000 uF and the input cap to 100uF. In addition you will need an output capacitor and this should also be a high value 100uF. You need an output load of say between 10K and 30K to get the results you appear to desire.

I have modelled the suggestions. You need only 10mV input to get a volt output.
