View potential customer (8)
I believe the answer is:
This clue is a double definition.
'view' is the first definition.
'potential customer' is the second definition.
(I've seen this before)
(Other definitions for prospect that I've seen before include "Chance of success" , "View - chances" , "Explore in search of something, perhaps gold" , "Outlook - search for gold" , "Likely candidate" .)
