Looking to be backup wedding photographer

I'm always on the lookout for other photographers who are willing to hire me as a backup or even as just an assistant. I've put out dozens of emails and phone calls to local photographers, and gotten very few responses. I keep hoping.

I also made offerings to local DJ and catering services, as well as entertainment services; very little response there too.

I want more work! I want to fill up a week with photo shoots upon photo shoots!
