Does Not appear to be a JAA licence just FAA licence that you have to convert. Notice it says on the website:
JAA Conversion:
Epic Aviation has an agreement with a flight academy in Europe to conduct your JAA Conversion. This will include your Frozen ATPL Written Exam, and CPL Check ride. Study Materials will be issued while at Epic.
**Cost of Conversion not included in guaranteed price.
So you need to allow for conversion, both time, effort and cost!
Consider a JAA Approved School.
