If you choose to take out a loan, you might want to look into a Career Training Loan. If you are already a pilot with a fixed wing license, you can apply for a rotorcraft add-on license, and you will not be required to fly as many hours to qualify for it. There are few scholarships available for students of rotorcraft. There is a non-profit called Whirly-Girls that provides women who have already gotten their private pilot certification with scholarships to help them achieve a commercial private pilot certification.
