This is so weirdly NOT unheard of. There have been quite a few cases where someone approached a painter, yard guy, handyman, or similar worker and asked if either they could do, or knew someone they could contact to do a murder for hire (of husband, wife, son-in-law).
I am always totally shocked by that, because (1) the person asking for the service is some otherwise seemingly normal person, (2) why would someone assume that these people would be or know murderers, and (3) why would they assume they could trust them not to reveal their intentions.
In fact, many of the cases I have heard of, the person who was approached immediately went to cops, and that's how the person was caught (through a recorded set-up). It only makes me wonder how often this happens and no one does tell, or they really do commit the crime.
