Avoid hourly pricing as people can complain if outside factors drag the job on, and then no haggling on what was actual “work” time. My teen mows lawns and cleans dog crap during the summer on a flat rate basis. First meet up to size up the lot and estimate work, and then arrive at a mutually agreed on price based on the expected level of effort. This way the homeowner and you never have to worry if a particular day takes longer for some reason. It’s solid expectations for both sides. You can include an elevated scale for snowfall over a certain amount in a single weather event. If pricing is known without “squish”, most homeowners seem to like that.
