Looking for construction contractors (free services) (Orange countty)

Hello everyone! I am launching new admin services for subcontractors and general contractors in the local area.
Before I market, I would like to find two subcontractors who currently do all their office work and need some extra hands.
Offering my services for free! I would like to offer admin services while figuring out my processes and how to best help my clients.
All I ask in return is for feedback and a testimonial after the month is over.
I have experience as a project coordinator and know a lot about the construction industry from the admin perspective.
If you run a business or know anyone with a contracting business please let them know! I am only taking two free clients.
I can help with things such as: change orders, client communications, invoicing, closeout documents, RFI tracking & equipment rentals, etc.
Reach out if interested and I would love to help you get your business organized! Thanks, Amanda
