You're putting way too much stress and thought into this. My house is open to DCFs from 6-6, m-f. Otherwise unless I've made an appointment with you, I'm off work and not "at the office". A parent showing up unannounced on the weekend looking for care will still be looking because I'm not going to even consider dealing with them.
You are running a service business out of your home. I'm not "on" for current or possible DCFs- I do things my way for the benefit of my family. If that helps clients, great. If not oh well.
If all else fails pretend you're in Frozen and sing "Let it Go" a few times
