Confianza

Por mi parte, tan sólo decirle que tiene toda mi confianza.
From my end, I just wanted to tell you that you can totally trust me.

I don't think trust is the correct word her...are other other options?
Many thanks in advance.

As for me, I just wanted to tell you that you have my total confidence.
... my every confidence.
