If cost is an issue, you might want to consider a below ground pool with a liner rather than a gunite pool. Add a spa, decking, and high end equipment and you can easily be up in the $40,000 to $50,000 range, depending on size. Talk to a few pool owners and pool builders in your area for more detailed information.
One and a half hours is much too long to cook the chicken at 350 degrees F. The time your chicken will bake in the oven does depend on the internal temperature and the size of your chicken or chicken pieces. Generally I bake chicken at 350 degrees F. for 30 to 40 minutes.
Place the seasoned chicken in the casserole dish. Cover the dish with aluminum foil and bake for one hour at 300 degrees. Baste the chicken once half way through. After one hour, remove the foil, baste again, and turn the heat up to 425 degrees. Continue to bake the chicken at the higher temperature for 20-30 minutes, or until the skin has achieved the desired level of brownness.
