customer selection: find or create

I'm working on a form to create offers for our customers. Sales is currently creating loads of duplicates because the search performance is poor and they are rather hitting the create button than look up an existing customer. Moving to elastic, offering a much better search experience, I want to disaccustom them from doing that.

My idea would be to decrease the presence of the create option by nesting it inside the search results (Option B).

What do you think?
