You Want To Pay Me What?

Okay, I have to vent for a minute. While playing around on the Internet and searching for production companies to send my demo to, I stumbled upon a casting notice. They want to pay the tv host $300 for an all day shoot. Is it just me or is that ridiculously cheap. What is the saying "you get what you pay for." My thought is that if you can get someone for that cheap, they must not be that busy and if they are not that busy, then shouldn't you ask yourself why?
It just blows my mind that someone in this business (a production company) would have the nerve to pay someone so little. Am I the only one that thinks this way? I welcome your thoughts...please.
