I need an analog expert to redesign a low-noise front end for medical
purposes (to measure EMG and EEG - signals in the low microvolt range). The
system we have has a million Megaohm (10^12) input impedance, 130dB CMRR,
and 12 bit resolution,  but the signal waves around too much if the cables
are jiggled.

I have seen systems that somehow minimize this effect, and need someone who
could help redesign such a front end on a contract basis.
