door knocking is the way forward, leaflet dropping is alright but doesnt get the same amount of jobs as canvasing.
i started part time at weekends and any spare time but you have to aim to be able to doit full time when it gets dark.
you cant say sorry customer not cleaning you from nov to feb it gets dark early!
they will want e relieable window cleaner, so work your b0llocks off to get enough work b4 it gets dark early.
From my experience alot of bungallows do there own windows so that might not be were to start, but this is just from my experience.
GOOD LUCK
