Balloons for ADS (Score 0)

Does anyone have a link for a manufacturer of said balloons. I have friend with a problem with local code enforcements when it comes to advertising along the street. I'm wondering if after a certain height they lose their jurisdiction to regulate ADs. If this is the case I would like to get a few of these balloons and hoist a sign up in the air. Also if someone is in code enforcement and would know about Florida state law behind it, I would appreciate it.
