If you have enough spare cash, enrol in one of the Barnett's or UCI courses to get that piece of paper. You might be able to find a bike shop that is a good employer and willing to let you wrench for them. But I suspect where you are, there are significant seasonal troughs where work might be hard to come by.
You'll also need to read A LOT to keep up with the (marketing-driven) "technological advances" in bicycles, especially MTBs. Your tool account also might need a boost -- having talked recently with a retired bike-shop owner who still keeps his hand in wrenching, a new tool is required almost every month.
