Every market is different. Some are going to be complete opposites from my market. For example, the guy we sub window cleaning too use to run his business in Denver. He says it was exponentially easier to get jobs from cold calling than in Kansas City. Different market. Different attitude. Different marketing experience.
If you approach (cold call) 100 commercial properties a week, get a business card or take notes about where you went, their attitude when you approached, if you closed business or not, etc. Then you’ll have a better idea of your ratios when you look at the data you compile over say 6 weeks.
The good news is that you’re in a huge market comparative to Kansas City. London: 8.8 million. Kansas City metro: 481k. With outlying suburbs 2.2 million.
You may find in your market that 50 approaches net 2 jobs. If 50 approaches net 10 jobs, you probably aren’t charging enough.
