What are you consulting on? If you are looking at mouse histology for a researcher at your university I would charge less than reviewing slides for a lawyer or providing your expertise for a biotech start up.
What would be a range for hourly rate, part time, helping set up a new company, lab developed test only? My name not medical director. Would this require additional malpractice insurance? Any resources you can point me to would be helpful.
I would say at least $300 per hour. Also keep in mind that if you're doing this as contract work (no W-2), then the taxman will come after a significant portion of this income since you aren't taking out for social security, etc. Also make sure your primary contract does not conflict with this venture. Hope it goes well.
