How can we help? What you asked you already found the answer. You say the free Campaign has helped to use the Signature code on your profile, that's very good.
Then start looking for Paid Campaigns in
Bounties (Altcoins) that accept Jr. Member, because most Bitcoin paid Signature Campaigns only accept rank Full member +.
I don’t think participating in paid signature campaigns will help you as you seem to have no idea on how to be a good contributor in the campaign. Learn first and expand your knowledge about bitcoin and cryptocurrency before you consider earning an income from it. I know once you gained real understanding about crypto, you will know eventually how to work in a campaign and become an asset in it.
