Since agents get paid ONLY when a transaction is completed writing offers for no closing is just work with no pay. I am sure you will find some agent that just got a license last week that need practice writing offers. Experienced agents will be a lot harder to find that will waste their time like you want them to.
I always recommend that my clients make an offer that will create a win - win situation in which both parties will be happy. Low balling is a tactic that makes the buyer and the agent look bad and gives Agents a bad reputation.
I am not sure what you are trying to do here. I hope you will explain a little more.
