Forget $50,000 it's creeping past $60,000 now, and is certainly thousands of dollars more once you budget for living expenses during that period.
I'd budget $75,000 for training/books/exams, living expenses and some cash left over "just incase" you don't get it all done in the minimum hours.
Don't bother doing the combined fixed wing ppl to heli cpl course to save you money, it has it's advantages in other ways but certainly not financially. You will only have 70 odd hours heli time when you finish compared to 105+ hours everyone else will have. Too make up this gap you most likely will have to fund this yourself, because most heli operators don't look at total aeronautical experience, just heli hours. And finding a job is almost impossible as it is already for the 105 hour guys.
