with/for

Are these sentences correct:

[color=red]1-With her, any painting her son produces is a masterpiece.
[color=blue]2-Any painting her son produces is a masterpiece with her.
[color=indigo]3-Any painting her son produces, with her, is a masterpiece.

They are supposed to mean:
She thinks that any painting her son produces is a masterpiece.

I use “for” instead of “with” in such cases.

Gratefully,

Navi.

‘For’ would be the correct form.
