There are no more signature campaign that accepts newbies except for Let's talk about the future campaign. Also, your post is out of topic in here but it seems like no one has replied you yet and I don't want to just keep you waiting for a reply.

Signature campaign is a good way to let people know that your website is out there running. But if you don't have a big company or a good service, I will not advice you to start a signature campaign. I see that OP owns SatoshiLottery which had a signature campaign in this forum already and has ended last week or last last week. I guess he doesn't need this thread anymore.
