I will send you to John

[azz]

a. Whatever I can't do for you, I will send you to John to do.
b. Whatever I can't do for you, I will send you to John to do for you.
c. Whatever I can't do for you, I will send you to John to do it for you.

Meaning:
Whatever I can't do for you, I will send you to John so that John will do it for you.

Are (a), (b) and (c) correct with the given meaning?

It seems to me that they are not. It seems to me that in those sentences you - and not John- are the person who is going to do the thing I can't do.

Many thanks.

(b) is appropriate.

'For you' clearly indicates that John is the implicit subject of 'to do' .
