Wait until you got a legendary rank and earning .1btc is possible for you.
signature campaign the best rate now fortunejack and bitsler and rate only 0.05 bitcoin/week
so you can't found signature campaign although legendary member payment 0.10bitcoin/week
Signature campaign isn't the only way for legendary members to earn money here on bitcointalk. Due to it's high rank people tend to trust them since they're risking their trust rating whenever they do bad things. Legendary is most likely to be accepted in Escrows, Campaign Manager, etc.
