Day one: you, a double garage on the side of the house, and $20,000. Buy a treadle shear, a pedestal drill, a pan brake and a MIG welder, quote the jobs you can deliver on time, order sheet from the supplier and hire a hand or two when you can. Customers ring for packer plates, kick plates, angle brackets, weld-on brackets and letterboxes, and every week the bills come out.
Meet your goals and you move up to a factory unit on the estate: an empty shed you lay out yourself, with an office, forklifts, a guillotine and a press brake, then on to the works with powder coating and a laser. Prices and wages are real Australian figures. It runs in your browser, with nothing to install.
