Scared, Skeptical, and have no idea

[Elizabethn]

This is a major boundary violation and considered unethical by every professional organization of which I'm aware. You don't engage your client's services, ever, period. Not as a favor, not for pay, nada, zero, none, never.

If you live in a tiny community where you "have" to do business with one another outside the t relationship, that is one thing. But I'm not hearing you describing this relationship that way.
