My question is, should I have the brrrr under a different LLC? 

Some insurance companies for multifamily properties pulled out of the market, while others offer significant wind and hail deductibles.

Major homeowner insurance companies denying offering coverage because of claim history. 

Denver is a great market and there are also several great PM companies here, just sayin! 

.  Go and call around to other landlords in the area or property management companies and get copies of leases and act as a renter and trying to understand what the requirements are and their best practices.  in our area, it is common to pre-lease 9 to 10 months in advance before the academic year begins and for tenants to pay every utility including water .

This should automatically happen if your escrow company is owned by the title company or if you use a closing attorney.

I'd encourage any investors (with positive or negative feedback) to contribute.https://investclearly.com/sponsors/mc-companies

Quote from @Maya Jones: This type of thing is like trash companies, you will hear it right away from your tenants if their car is blocked in by snow.

Could you please recommend a company to take a look at it?

There are a lot of things that need to address for a PM company between compliance with the state, local rent control in a lot of your area you'll be covering, a lot of competition that is in your area, marketing/ads, and so much more.
