Lol mate, not too hard, you get a contract running up with your canvasser, come to an agreement - you know what days he/she does, give them a couple of days when you are free to do the work, let them book your quotes and appointments and you just turn up. I think by the guy that was saying earlier hes getting on quite well with his guy. Just terms and conditions that you both feel happy and comfortable with.
Just think its a question of working along side somebody that you feel comfortable with - you musnt look as a canvasser as a workhorse, he/she is part of your business, so you need to build a working relationship with them, and that then builds trust and commitment.
When I do commercial calling, I want to know what the outcome is - I need to be in touch mentally for the people I work for, myself I need to build a personal relationship with anybody I work for, otherwise I feel no point.
Hope that helps
