I want to hire someone to organize my expenses using expensify.

I travel a lot. I've tried to organize all this travel using expensify, but it's just too complicated and takes too much time. I want to hire someone to handle all the complications for me. I'm willing to pay generously for this, but want someone really really competent who I can rely on to always act ethically and document everything carefully.
If something cannot be documented to the standards required for auditing etc, I'd rather pay it out of my own funds and not get reimbursed, than to submit something where anyone later could quibble about whether it was legal.
I have plenty of money and would be happy to pay generously pay someone highly competent to do this for me.
Does anyone have an idea how to get started?
PS. DO NOT CONTACT ME ABOUT THIS IF YOU ARE NOT PREPARED TO MEET ALL OF THE CONDITIONS ABOVE.
