If you are familiar with TAFE then you should be able to enquire there about a business or accounting course, surely they will have something along the lines you want!
And you may be eligible for a business loan but on a pension that's hard, but a bank lender likes to see a business plan laid out, that includes how you are going to service the loan, what type of saver you are, they either consider people viable or liable.
But good luck with it!
