# Guides

Practical guides to hiring a service company. Each one is checked before it is published and cites its sources. They are free, and you do not need to send a request to use them.

## Published guides

- [Janitorial RFP checklist: what to send cleaning bidders](https://citypreferred.com/guides/janitorial-rfp-checklist). A working checklist for a janitorial RFP: the eight sections to include, a task and frequency table to adapt, and how to compare bids on equal terms.
- [Where US service companies are: the 2026 count](https://citypreferred.com/guides/service-companies-by-city-2026). 1,537,797 service companies in nine trades, counted by state and city: which cities and states have the most.

## Tools

- [Cleaning scope calculator](https://citypreferred.com/tools/cleaning-scope-calculator). Turn floor area and frequency into labor hours, with every assumption visible.
