I was in production, not development, but I think this might be what you’re looking for in terms of information for your specific genre.
As far as I know generally, you will to have sent a synopsis and treatment for your idea beforehand through an agent. It is very rare that producers let people pitch to them who haven’t vetted by someone they know and trust. Also, you can’t just send ideas to a production company or network. They have to protect themselves from lawsuits, so they will not accept unsolicited work.
Perhaps when you read the link I put above, you could send an email introducing yourself to the blogger. Making connections who can help you (and that you can help in the future) is the hardest part of the whole process.
Good luck! :D
