You're stuck in an hourly mindset. If you pay someone to build a house, and they complete the house, they're done. They get paid. Whether they build it in 1 day or 200 days, the price is the same.
Getting paid for time is a trick that you need to surpass. Get paid for what you produce. That is the primary difference between businesses and individuals: the non-correlation of time and revenue for a business versus an individual.
