Hm.. I think there's no more ,but there is a contest photo editing ,creating logo contest which if you have skills you may try it who knows  if your work is chosen and win other than that i dunno just try to look at the services section and on micro earnings .i don't think that jobs like signature campaign doesn't satisfy your earnings .other works buy and selling goods and things .
 Why don't you try a real work outside bitcoin that may gave you more works and bigger salary amounts .
I don't want to offend im just suggesting =)
