If you have a longstanding relationship with an existing vendor and your local government does not require you to re-bid for the services of this vendor periodically, then you can provide a quote from that vendor without providing two other quotes. Unless your government has no written procedures on procurement, your application must demonstrate compliance with these procedures by providing copies of the official procurement procedures you are following along with an explanation of how you will follow these during your proposed grants project. In the absence of any written procedures, you must provide a description of your standard procedures along with a separate written explanation of how you will be adhering to these.
