Does anyone know other expressions for "promise you the moon", or "pledge my first born", etc. I have a difficult client I need to say this to and I want to sound clever or witty. :) Thank you

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
The cliche phrase is "I will bend over backwards", though I don't know how clever or witty that will make you sound.

I will go the extra mile.
I will give it 110%.
