Service Areas — Nationwide & Southern California

GERC works nationwide. Our office is in downtown San Bernardino, California, and almost everything we do is delivered remotely — which means where you are matters far less than what you are trying to fund or win.

Nationwide services

These are federal or otherwise geography-neutral. We take clients in any state.

Markets we serve nationwide

We help small businesses win government contracts in all 50 states, Washington DC and Puerto Rico. Each page below covers that area’s own registration portals, certifications and buyers, and we serve every one of them remotely.

California-specific services

These are state programmes and apply to California businesses only.

Forming an entity outside California? Tell us the state and we will confirm what we can handle there.

Working with us remotely

Registrations, applications and proposals are built from documents and conversations, not site visits. Clients outside Southern California work with us by phone and video, receive the same written deliverables, and are not treated as second priority.

Documents are delivered in ADA-compliant formats, and financial models are handed over as working spreadsheets you can update yourself.

Where we work in California

We work with clients across the state. These pages cover what government buying looks like in each market, who the buyers are, and which certifications matter locally.

Who you will be working with

The practice is led by Dr. Shirley Ayangbah, who holds a PhD in International Economic and Financial Law and an MA in Economics. Engagements are handled directly rather than passed to junior staff.

If you are weighing up whether to hire anyone at all, we compare the options honestly, free ones included: companies that help with government contracts. And if you would rather do the Cal eProcure registration yourself, here is the full step-by-step walkthrough.

Engineering and construction firms: see the dedicated guide covering SB-PW certification, DIR registration, certified payroll and apprenticeship compliance.
