Net income one generates in refurbished atelier (1-6)
I believe the answer is:
e-tailer
'net income one generates' is the definition.
(someone who makes money on the net)
'refurbished atelier' is the wordplay.
'refurbished' indicates an anagram.
'atelier' with letters rearranged gives 'E-TAILER'.
'in' is the link.
(Other definitions for e-tailer that I've seen before include "Shop online" , "Online merchant" .)
