Thanks for the replies.
So... should I charge her for the design?
Or... how do I reconcile the facts that a) there must be specs b) this is a creative process...
If I wish to make the point to the client that this is a creative process, do I do a design for her pro bono and then let her show the design, i.e. specs, to other "contractors"? That seems contradictory to me.
Or do I do a design, show it to her but not allow her to keep it to show other "contractors", hand her a written bid with a dollar amount and ask her to call me?
Or do I do a walkthru of her property and just ask her where she wants a light placed, etc?
