Are you on payroll or are you invoicing them? I say this because I could imagine maybe the legal issues are the government determining it is not a real contractor but a "fake employee". IMHO, if you are invoicing, OP reasoning regarding pricing stands, regardless of the dynamic day-to-day, since you are paying social security, pension etc. out of your own pocket. If not, please disregard.
