fantastic advise RO-sheen.
its good to canvass your own work,but if you have a bit of money stashed and you want a ready made round, buying from a canvasser is a good bet.
as already mentioned, doorknockers do this.
i can vouch for them as my friend used their services and they were very professional and above all accountable, if your not happy with anything they get for you they will refund it or replace it, same if you get any cancellations.
they charge twice the amount canvassed and their minimum is a £500.00 round which will obviously cost you £1,000. they got my friend his round over a period of a few evenings and we are now in the process of doing the first cleans which are going well.
obviously its cheaper to canvass yourself as it costs nothing but your time,but 8 weeks after spending the money my friend will be earning a very good wage,its all about what your needs and budget are.
if you google for doorknockers im sure you'll find it as i cant lay my hand on their web ad at the mo.
hope this helps
