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.
A good temperature to bake your chicken at would be 375 degrees for  30 minutes. You can use a meat thermometer to check the temperature  which should be around 165 degrees. generally bake mine at 350 degrees for 35-40 minutes and then cut at the thickest point to see if the juices run clear. If you bake too long it becomes too dry. I always bake my thawed chicken breasts at 375 degrees for 50 min. and they come out juicy and fully cooked.
