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.
Remember, you want the chicken to slowly bake all the way through; baking on a significantly higher temperature will cook the outside too quickly and make the breast dry. If you are not following a recipe, know that a standard oven temperature for baking a chicken breast is 350 degrees Fahrenheit (177 degrees Celsius).
