Post my message to 457 blogs

I can provide direct links from 1 web site to 457 blogs. Some of the blogs require you to register on the groups before posting the message and it this case I would be using my own name to register and you can create a password. If the blogs do not allow anyone to post then I would need you to send my message to them via their CONTACT US link. I need someone who can provide quick service on this project.
