Hello!
1st of all u need to have patience. Try to unlock levels on crowdflower by doing tasks. Once, you reach at level 1 you will be able to do so many tasks, after that you will yourself understand how to work. For more info, visit Forum -> Tasks . That could help you alot.
For offers, I dont think they pay us sufficiently. But if you really want to earn more, you have to do tasks instead of surveys.
So try to do 0 level tasks and earn level 1 badge. Checkout if there is any task for 0 level here :
ClixSense Forum
Goodluck
