Your post is from over 2years ago, it has taken me nearly that long to get my Irish license.
There are different routes to achieve your dream.
My route started with flyspains 2 week course back in april 2014, this gets you a UK Club pilot (Power) rating. Week one is Elementary paragliding.
You can then practice legally in Northern Ireland not going more than 2 miles away from takeoff.
Then after some practice, back out to Algodonales in may 2015 for a 1 week paramotor holiday in which i was put through the UK full pilot test, which is a practical and written exam.
This can then be transferred into an Irish license exemption letter. (with a medical and insurance)
Its not easy or cheap to do all this. My wing cost €2K and Motor €4K both second hand.
Step one for me before buying anything was to do that first full time 2 week course, you will learn to fly and use paramotors safely with instructors who are full time professionals.
Then you will have some information about the whole thing.
The very best of luck, its an epic adventure
