I recently became a pool owner and shortly after had to go to pool school. I was talking pool with someone that was impressed with my knowledge on pools and was asked how much I charge. I tested this person's water, told the person what to buy and how much to use, and gave a few tips for free. But if I were to keep their pool looking good, I would like to make a little money doing it. I live just a few miles from this person, so it wouldn't be out of my way. The charge would really just be for my time and testing chemicals. I have never had a pool person to even begin to know what the going rate is here in East Texas. Does anyone have a suggestion on a fair price?
