John, I run a pretty successful driveway company and have various routes to market, I studied this industry long and hard before I started and also sold the product for Anglian before which involved door canvassing, I'm very coy about sharing these routes as I'm sure my competitors would jump on them if they knew however if you want to pm me your number or email I can share with you, we do over 100 installs a year for a lot more profit than 1k, I think at 1k your pretty cheap and I presume your not vat registered so even cheaper, build confidence and value and you can charge more, never ever cut corners like the rest and have a great focus on after sales and they will come back, I had a problem on a driveway we fitted over a year ago in September there, customer called with a problem as his son had crashed into this dwarf wall we build, it just so happened we were working not to far from it, it was fixed within 2 hours free of charge, things like that are worth doing. They breed confidence as people talk and a reputable driveway company is rare these days, I ain't had nothing back from doing that fix yet but it will come I'm sure of it, the amount of Cowboys in this industry is incredible. There's your usp right there, do it right first time, if anything does go wrong you must fix it asap
Back to canvassing and I agree with above, NOT canvassing your area of install is madness however there's also nothing stopping you canvassing an area where you done an install 6 months ago!
Canvassing has changed 10 fold since 10 years ago, people just don't trust it especially our industry and it doesn't breed confidence, but there are ways to do it. however after all that you or the canvasser need to be good at selling, anyway by all means drop me a pm, I could give you 3 or 4 routes which I guarantee you will add 100k to your turnover.
All that said though by doing what we do will obviously make you vat registered which in turn will double your workload as you will be an additional 10% more expensive overnight with vat meaning less sales, I was selling 7-8 out of 10 before I went VR now I'm about half that so have to do more lead generation and more appointments but it's worth it.
