Slightly different as I'm in hairdressing, but I just recently went on a colouring course and pricing was a topic of conversation and there were a couple of mobile hairdressers there. When asked about pricing they said they always priced themselves lower than salons... to which the tutor replied 'I don't understand why mobile charge less than salons... if you were have a chef come to your home to cook for you, would you expect to pay less or more than going to their restaurant ?' To which I think we would all agree that you would expect to pay more... I completely agree with her as you have to get there, carry around all of your stock and products, they don't have to find childcare etc etc... x
