Back in the day, you bought a second hand van, the best you could afford, printed a few flyers off at home, cobbled a system together then went doorknocking probably basing your prices on other cleaners.
These days the lads round my area invest in a brand new van, fully fitted system, embroidered uniforms, four colour double sided flyers, rent a unit, go on a training course and jump straight in with massive prices.
If you were starting out again which approach would you use?
