Is she in a hurry? I converted my US FAA CPL to EASA PPL over a couple of months time with a flying club in Bavaria. C-172 rental rates were very reasonable and the club was a good group of locals. Instructor costs were minimal. I didn't keep tract of costs but I doubt it was over 2000€, including annual club fees. Lots of flying clubs in Germany. She should check her area. Basic German is helpful.
