Can you answer the questions asked above ?
If your family makes less than 75k an elite college - if you qualify for one - will be cheaper than a public university.
In addition, your goal should not be to graduate as fast as you can, but to use your time in college to get the experience, connections and skills needed to position yourself for the best possible job after graduation. Rushing through college doesn’t allow that. It means building leadership skills and positions, study abroad research, internships.
