Your work to upgrade is admirable but you probably want to separate it from the showing process. 

I'm not personally in a position have need of your skills, but I admire this approach.

I admire you for jumping right in and not letting fear hold you back.  

Pick someone within the field of REI you admire and implement their systems and processes, tweak them as you become more experienced. 

I'm sure they will admire your interest in working in an internship with them. 

Your eagerness to answer people's questions is admirable, but I think if you watch some of the conversations as they unfold, you'll learn a lot more of the technical aspects of accounting and taxation by reading and absorbing the answers from others.Most of the CPAs here have key word alerts and they will chime in on 99% of the tax related questions.  

Hi Andrew, I admire your decision.

I admire your ambition and fearlessness, but I think you need much more cushion for unanticipated expenses which is certain to happen. 

First off, truly admire you guys here!  

Sounds like an admirable thing to do and a win-win on both sides.
