We are the material supplier. We contracted with the sub-contractor. Job is a charter school in Indiana. The school has a loan thru a local bank, and that bank represents 3-4 of the investors (these individuals are unknown to me). The school is also trying to get a loan from IFF-Detroit (provides financing for non-profits). I need to know who the surety on this job would be, and whether or not to proceed to secure our lien rights or to file a bond claim. I have, literally, only a few days left before my time to do something expires, so I need an answer quickly. Thank you for your help.
