The secret, if it is a secret, is not to be fearful of charging the right amount. If they say no, you never had it in the first place, and you should'nt want it either. Sooner or later you may feel you are not getting paid enough and began to do a sloppy job which could be bad for your reputation. I would rather have a reputation of charging too much than one who does unsatifactory work. I live in an area that one of highest unemployment in the country, yet I can get an average of $40 per hour. Just keep on asking and before you know it, you will have customers who will pay you right. Just do unto them as you would like them to do unto you.
