We have 3 vans operating, & I now spend most of my time doing quotes i.e. actual visits, marketing, database & doing the paper work / running the office.
It works out quite well for us but you do have to constantly keep your foot on the gas & think about marketing all the time.
It does mean I can give that personal touch to all the customers and not feel rushed when seeing them, also giving time to upsell & talk about our add on services
On the downside you have to bring in a massive amount of work each week, so can't afford to get lazy about it,
