Stan,
I've got many jobs that established trad users would've stayed clear from; awkward stuff from ladders or leaded jobs.
With the pole, I found these have turned into some of my best accounts.
For example, we have a small real-leaded windowed hotel and it used to take two of us two-hours of tough work to handbash the lot. I was given this job because the previous window cleaner didn't like it.
I can now do it bymyself with a WFP about an-hour-and-a-half and the results, although rarely perfect, are far superior than what you could achieve by handbashing.
For a small outlay, you could really make a killing in your area; I reckon; just by targetting those properties that other window cleaners avoid.
