It sounds like the solenoid is bad on the starter. I would recommend replacing it. The starter is located about oil pan level and bolted to the bell housing.
Let me know if this helps. Also, if you want to be sure it's the starter, have a helper turn the key to the start position and check to see if you're getting power to the small wire on the starter.
If you are getting power, it's the starter.
