How to implement RUBS for utilities

[Tia Wilson]

Hello everyone 

I bought a duplex last year near UH. The previous owners paid all utilities since everything is on one meter. I was able to keep that going but its now cutting into my cash flow. I thought about raising rents but I'd have to increase over $100. And in my neighborhood im almost tapped out at market rent already. What id like to use is RUBS but cannot find how to implement it. Do I formulate the cost myself or you have to hire a company? If so anyone have recommendations? I've searched everywhere for info and can't seem to find a simple answer. Thanks yall!
