Plenty of schools would love someone who just wants to build time. Ive done that at my school for a number of students from Europe who mostly just wanted to build time. (Long Island NY) We charge 222.80 an hour for dual time in the R22.
Is she looking for training, or just hour building? If she is looking for hour building and knows she wants a large amount of hours, I suggest she neggotiate a bulk time discount with a school, hey it can't hurt to ask.
Instructors love a student like that, its a great chance to go new places, so feel free to shop around because thats a hot commodity.
If she wants instruction then may I suggest one of the larger schools, Hillsboro Aviation, Helliadventurs, Vortex, etc etc. Well established, large, bigger fleets, good maintenance.
