How much would you professionals charge for something like this? I live in Knoxville, TN, in case you want to take cost of living into account.
It may not be possible to answer this question legally in the USA on a public forum as this could be considered price fixing. Even when it is a general ballpark question. The penalties for price fixing are jaw-droppingly large.
I am not a lawyer, and do not live in the USA (and therefore could well be wrong). I came across this from a similar question that seemed equally innocuous on a professional (veterinary) list-serv that I am a member of.
