## Direct answer

To start a data centre staffing agency in Chicago, form a Illinois entity, register for unemployment insurance and withholding, carry workers' compensation, and fund the payroll gap. At the Illinois median pay of $47.87 for electricians, ten contractors tie up roughly $160,023 before your first invoice is paid.

## Local facts about Chicago

- Illinois licenses private employment agencies through IDFPR and the Day and Temporary Labor Services Act imposes equal-pay, notice and safety-training duties on light industrial staffing.
- The Illinois day and temporary labour rules require pay parity with a client's comparable employees after 90 days, which must be priced into the bill rate from day one.
- Chicago's derivatives and trading community is the deepest quant market outside New York.

## Registrations and licensing in Illinois

1. Form an LLC or corporation with the Illinois Secretary of State and obtain an EIN
2. Register with the Illinois Department of Employment Security for unemployment insurance and with the Department of Revenue for withholding
3. Register under the Day and Temporary Labor Services Act with the Illinois Department of Labor if you supply day or temporary labour, and carry the required bond and insurance
4. Chicago has its own fair workweek and paid leave ordinances that reach covered employers, including staffing suppliers

## Payroll and compliance

- Equal pay obligations for temporary workers on longer assignments change your margin maths — model the pay step-up before you quote a bill rate
- Detailed assignment notices and record-keeping are mandatory, not best practice
- Penalties for non-registration are meaningful and enforcement is active
