Hi Jupiter
i did mine with http://www.australianskillsassessments.com , A small family business who were really helpful and set in three stages, first was a simple written application, 2 nd was detailed cv and references and qualifications etc, and 3 rd was a Skype type interview/ watching me perform a hair cut etc followed by a theory exam in which I had a few hours to return completed. Cost about $2000 if I remember right. It took about3 weeks in total for me.
