Tbh this attitude won't get you very far in regards to signature campaigns (and in life in general for that matter). It's not like bounty managers are desperately looking for users to fill their campaigns - they are in the comfortable position to choose from a big pool of good posters and what best fits their needs or the advertising companies needs.

With you being a Jr Member, it will be hard to find a BTC-paying campaign right now as you can see in the first post of this thread. You would have to crawl your way up the rankings first.
