Hi,
I'm an expert Unity developer, and would be happy to carry out this code review for you.
I have successfully brought games to market in the past and have some currently on the google play store, one of which with close to half a million downloads.
I have completed the Unity certification and am currently going for the 'Unity expert game play developer' certification.
Happy to spend a bit of time going through in more detail what you require via chat. Even if it comes to nothing, it's all good experience.
All the best
Chris
Also I'm based in Ireland and so would be available/online during office hours in the midwest (I think Denver is midwest, however I might be wrong there).
