do you have to pay $110k to buy this courier please business if you just get $50-$60k net income p.a? I know someone who is working for post office as contractor, they could get for $1000 a week for no problem by working 5 days a week as delivery guy. the post office provides uniform and van, you need ABN and fill the fuel.
if you just want to get a Monday to Friday work, you don't need to invest that much money I believe. I hope this info is helpful to you to make decision.
