Check the "Services" section of the forum. You have the best chances of getting to know new openings on the Signature campaigns there and there is also a thread that keeps track of new openings Here:

Overview of Bitcointalk Signature-Ad Campaigns

But please dont go for the bounties section in Altcoins. That area is filled with projects that are not even worth calling the same. Majority of them will be failures and end up being a spamfest. Honetly I dont have anything to share from that, but Bitcoin paying signature campaigns are what my suggestion is.

I see you have received enough merit, so keep that up and you should do fine.
