You need time, and $$$
You have to do all 14 theory exams, and at least a self study and finish up from an approved school such as bristol www.bristol.gs Then CPL training to proficiency and a 15 hour multi IR. Plus an MCC course if you want to apply for an airline job.
Budget around 6-8 months and about 25000 Euro at the minimum
Send me a PM if you want further info (I did it in 2002)
