Gosh, I cannot imagine what would be unappealing about the opportunity for a tradesman to devalue the price of their labor and experience the small-but-inherent risk of catastrophic injury any time a ladder is involved in exchange for the chance to pick up a spare tenner… (Beyond that, even if they’re already in the area, by the time they pull up the truck, load and unload the ladder and actually do the job, the per-minute rate is probably already a fair bit worse than what they would earn from real customers - it may seem to you like you’re offering an easy job at $10/minute, but it’s probably a tenth of that all in from their perspective.)
