is there an idiom?

Hi,

Is there an idiom do express the idea that somenone "doesn't spare any effort, work" or "is always willing to help".

For example: "Linda 'doesn't spare any effort' to help everytime we call her.".

Thanks.

I'll start:
She always gives her all when we call her.

You could say she is a willing horse - from the phrase " willing horses carry the heaviest loads".
She could also be a tower of strength.
If someone knocks themselves out when doing a job they give it all they've got.
