I am working on a project and not getting paid. I am out about 300k
Finding the bonding company takes some "detective" work - if it is a public entity (i.e., federal, state, county, school or other public agency) it is much more straight forward, and usually a call to the procurement or facilities division of the agency will produce the payment bond fairly quickly. A freedom of information (FOIA) act request can also be made, but that will typically take 30 days or more.
Please feel free to reach out to me privately for any further questions, or to discuss retaining our firm for this matter.
