I think the first thing you need to do for getting a good profit is pump your account at least to the Member level. And after that, you should choose signature bounty campaign. Or you can participate in Twitter and Facebook bounty campaigns if you have good accounts on these social networks.
Now it is very difficult to pump any account, because of the situation with the merits. For example, I as a recent member of the forum is unlikely to surprise with something old participants, so they gave me merit. Therefore, in my opinion, the advice can be given only one: to work with what you have. Take a signature, and in the same bounty to participate in Twitter and Facebook campaigns. And pump Twitter and Facebook accounts
