Dream job would be to start a geo engineering business, helping local farmers with flood and draught mitigation, bushfire prevention.
Don't have the money to buy a bulldozer dump truck and excavator that I'd need for the earthworks.

I reckon 50k would be enough to start it.
Small bulldozer medium excavator, dump truck, bunch of greenhouses to cloning and starting seeds, a big new woodchipper etc.
