Two schools of thought
Option 1.
Build a business quick, do it cheap get lots of customers, the down side is those customers will always pay peanuts.
Option 2.
Build a business slow charging a reasonable price, those customers will always expect to pay those prices and you have more time to do a good job as you have fewer jobs per day, the downside is your business may not last long enough.
I have taken option 2 now in my second year i believe its a long term thing that i discovered on this forum and it made sense to me, the other thing is i would resent working for peanuts, and it is a service afetr all, last week i gave a lift to the local cafe to an elderly customer as he was about to call a cab, would i have done that if i was charging £17.00 per room, probably not i would not have had the time.
