Travis, there are better ways about going about asking landowners permission to hunt. Like in your scenerio above.

Sir, I'd not only be willing to bring all my garbage out with me, I'd be honored to assist you in cleaning up your property. I could patrol it and keep others out who may cause damage or leave garbage and I'd be willing to help you out in any chores that may be needed. etc. etc...etc...

You have to have thick skin and be professional and polite.
