Comp package consultant to advise startup exec candidates?

A need keeps coming up for my leadership coaching clients and contacts who are considering new roles, and I'm not sure where to direct them. They want someone who they can pay for a couple hours of time to help them - understand the comp landscape, especially VP-ish levels at pre-IPO companies, mostly headquartered here in the Bay Area - think through how to talk about comp in final negotiations - evaluate offers, especially the equity part of the offers - and sometimes, how to work with recruiters and retained search in a savvy way, and/or how to navigate a transition in the everyone-knows-everyone VC-backed world. Who do you know who might do this work?
