My husband is a self employed painter and decorator,he has been doing this on and off for 20 years but self employed in our own little business for the last year and half,we are a family of 5 having 3 teenagers and want to move out to oz,am i right in thinking he has to do the tradeassess(we have the forms for this) first and what does this involve,also i am a bookbinder but havent done this job for 18 years although i still could and have a letter from the company i used to work for.We want to come to Adelaide.After the tradeassess do we put in our visa application and what sort of visa do we apply for as we noticed painting and decorating is a job in demand.There are so many to choose from and there is so much to take in.
