One giving party no rupees (5)

Ross

I believe the answer is:

donor

I'm a little stuck... Click here to teach me more about this clue!

'one giving' is the definition.
(I've seen this before)

'party no rupees' is the wordplay.
'party' becomes 'don' (I can't justify this - if you can you should believe this answer much more).
'no' becomes 'O' (O resembles 0).
'rupees' becomes 'r' (abbreviation for rupees).
'don'+'o'+'r'='DONOR'

Can you help me to learn more?

(Other definitions for donor that I've seen before include "Philanthropist" , "blessed person, relatively" , "One contributing" , "One who gives, perhaps blood" , "A giver, perhaps of blood" .)
