It’s really simple: you send a query letter.
Companies DO NOT want to see your screenplay; that is the “unsolicited material” they don’t accept. They’ll accept query letters all day long.
Do your due diligence: find out who you contact, and send your query letter specifically to that person (or department). That’s the professional way to get your foot in the door and, ultimately, to get the company to ask to see your screenplay.

Unfortunately, you’re a poster child for why it’s so difficult to get manuscripts in front of agents and studios; you say you’ve been ‘ripped off’ which is a HUGE red flag and wave-off. Nobody wants to deal with a problem that could lead to a lawsuit.
Depends on which Wrangler you’re talking about.
One of the great things about California’s Department of Fish and Wildlife and California’s Department of Food and Agriculture is that they offer some great classes, workshops, and information that is really well presented.
The California Department of Fish and Wildlife, U.S. Forest Service, and Society for Conservation of Bighorn Sheep (SCBS) are looking for volunteers to assist biologists with a bighorn sheep count in Los Angeles and San Bernardino counties at the end of February (February 29 through March 1st). It’s the last weekend of the month, and the event will go on Saturday evening and all day Sunday.
