We are a material supplier. We did some shop-drawings, including estimating and engineering work related to our products for a Sub on a project in AZ and sent mock-up samples. The customer was advised if the project was canceled, they would be charged for these services. They then informed us they do not want our product, and state they have no money to pay the cancellation fee so were going to pass the invoice on to the GC and Architect to pay. We need to know if we have lien rights in those circumstances.
