I would like to do some freelancing in my spare time with a view to quitting my job and doing it fulltime once it is up and running. I am worried that clients aren't really going to like the fact that I will not be able to dedicate a predetermined number of hours per week to their project and will only be able specify a vague 10-20 hours per week timeframe.
Do you folks have any advice on how I can best handle this?
