if i was deperate for a job and decided to deliver leaflets (solus) i would charge around £100 a 1000. i wouldn't make a lot of money, bout £500 a week on a 5 day week, would be long days if they were average semi's. i'd make good money on the terraced houses, but lose out on the detached ones so i would make sure there was a mix. amazes me how these companies say £40 a 1000 without even asking where you want them delivered.
heres the math
on an average estate, semi detached newish build, with 2 car length driveways it takes around 8 to 9 hours to get out a 1000, thats without jumping the gardens and fences.
and thats without knocking and getting a signature.
i personally would never use a leaflet delivery company.
best and cheapest way to get leaflets properly delivered is employ someone full time. and even then you would need to regularly check up on them when ever you had the chance.
