If you are really busy and are getting 99% of your quotes a word to the wise would be YOU ARE TOO CHEAP, put your prices up and reap the profits, if they want you they will still have you, and if they don't, well you will earn enough money from the price increase to have a day off or look for another custy, I PROMISE it DOES WORK!!!!
