Answer:
$30-$80 an hour.
It really depends on where you live, but generally the average price is $60 for an hour. If you are interested in getting a better price, and willing to take a chance that it might not be quite as good, you could try going to a massage school student clinic. They will charge around $30-$35 for an hour massage. If you are lucky, you may even get a massage that's better than one from a professional. It's worth a try.
