I would find out all the Companies in your neck of the woods and fire off a letter to each and every one of them, then after about 4 weeks repeat it, that way you are not harrassing them but showing you are keen, the Auz CAA probably has a list of approved Aviation companies on their website that you can get contact details from, Our CAA has in the UK, but try to pin down a name to send it to as well, because that shows you have looked into them.
