I don't know your age/situation etc, but keep applying and def do the trip. Dress sharp and don't bull****. It's a different job than you've been doing in so many ways.
Cheap flights booked in advance and 4 or 5 days in a backpacker or caravan park will keep costs down.
Nepotism is awesome! Know anyone at any joint? Get on to them.
Make sure your CV is succinct and to the point. 1 page is great.
The move is a challenge, and will take some adjustment particularly coming from the safe confines / routine of a flying school. Hang in there at the 3-6 month mark as the homesickness will pass.
If it takes too long, get a job instructing again. 1500 looks better than a 1000 and so on.
Grade 1,META and IRTA are all good things to aim at and will enhance your prospects although if you hate instructing, do everyone a favour and steer clear.
Good Luck.
