I reckon 14k is a bit ambitious for drawings for one truck, especially on start up. My old guvnor reckoned on splitting the cheque like this.
I never saw a ratecon with max earnings every week
week 1 for truck finance
week 2 for fuel.
week 3 for tyres, insurance and maintenance
week 4 for trailer, admin, tax and drawings.
You get your bonus on a 5 week month but you still need fuel and tyres
That has to last for 90 days.
