I say go for it. I am also owner/builder and planning to break ground this December. I have found that networking is great. I have lived in my town for 52 years, my ex was a contractor, and I am and have been a high school teacher. Many of my students parents are into construction both home and pool and have been great at giving me advice, direction, and many leads. I always checkout everyone with the BBB and by word of mouth. I am finding that people are very good about helping. I have built two homes, but this is the first inground pool. I think that you will do fine. It will probably be very challenging, but many of us love a challenge. I say take it slow and be very selective. Be patient with yourself and with the others, but demand the job be done to your satisfaction. The houses I built were challenging but none could match the craftmanship, as I was on top of everything done and made sure I knew what I was doing, just as any professional would do. I listen and take in all advice, then I weight it and calculate it compared to all other.....check, check and recheck with others then proceed. You will do great and keep me informed as to your success. Remember to ask pool owners "What would you have done different if you built again".
