Keep canvassing in the new year, every evening get out and door knock, I built my round from scratch canvassing and it worked really well, but you have to be prepared to graft, it will be demoralising at times, but slowly but surly you'll get a small round together. Be polite and friendly and you'll be ok !
I started with the traditional method for years, and personally would do the same again, cheap start up, and means you can master the squeegee and ladders for when wfp can't be used etc, I also still use the squeegee and ladders for many custimers who refuse to have wfp, this in turn means more work and better prices. So maybe stick with the traditional method till September next year when it starts to get cold again.
When it does come to getting a pole system, check eBay for second hand kits, or try 'pure freedom' they sell diy kits for a reasonable price. Remember you've then got to worry about all the maintainance and making your own pure water, bigger costs etc, water bill rises. I would definatky start traditional mate, get some money behind you, and get a solid base of customers, don't get lured into a full blown setup strait away, I really feel that will benefit you in the long run.
Good luck, and keep going, come spring the canvassing will pick up a lot, I started without a website or Facebook etc, and only this year bothered with a website, I found canvassing is by far the best way to gain work, so far my website has got me a big fat 0 customers ! Of course time will tell, Google rankings are imlortant etc.
Lastly, where are you based? Someone on here may be able to give you a days work to learn the ropes...
