Associates Degree: Nurse vs. Physical Therapist Asst. in PA? (already a massage therapist)?

I intend on having my own business someday doing bodywork, which is what I love to do, but this job doesn't come with benefits and a stable salary. So I was thinking in getting a 2 year degree since I already have some gen ed credits, in either Nursing or PTA..but i can't decide! Both seem to offer starting salaries at 40-50K from my research online. I think massage therapy compliment both well, and I am interested in holistic nursing, but PTA seems a lot easier. Anyone in PA or elsewhere having any input? Anyone's advice is welcome here! Thanks for reading, :P
