df1,
I did that myself. It took me 7 months to get everything done full time. I mean, full time distance learning. I was able to put 6hrs/day into studying. The school I attended told me that a minimum of 15hrs/week are required to pass the tests in 10 months.
I suggest that you pick out a school in the US or UK depending where you want to sit your exams. When I did mine I had to travel to the UK twice for the brush-up and exams, that's expensive ... In the US you have : Delta Academy and Naples Air Center, both in Florida.
Almost all schools have their materials on CD-ROM these days, so don't worry about that.
A good price is 1,700-2,000 UK pounds for the course.
good luck,
