I started with basic gear mig bandsaw drill old mobile welder etc. To start with I took everything on I could do. Lots of agricultural work and gates etc. I reinvested as much as I could and over time got ironworker guillotine and folder . Word of mouth was best advert I found. I started before mobile phones and Internet were common. I think Facebook is a good place to start putting up work now. The other thing you need is luck. Sometimes you're just in the right place at the right time
