Hi,
the price depends on how good you are at retaining & absorbing the information, I would certainly not budget for 5k for your training as if you do & that is all the money you have it could mean you don't finish the course.
I'm not familiar with which school is best in your area, but go and see them & have a good talk with the instructors before parting with any money. On the subject of money, don't pay for training in blocks, just in case the school goes bust.
I would have a trial flight first, to make sure it is what you are expecting, then get your medical sorted first & get your head in the ground exam books & get them out of the way ASAP.
Lastly, enjoy the training!
