I used to work for ChaCha...but things have really changed over time and the income is no longer worth my time. I used to pull in 400-500 a month working a few hours a day. Now, I could probably make 1/2 and work a lot more hours. I have not logged in for months. I would say reasonably, you can expect to make 1 or 2 bucks an hour, especially starting out.
It is important to take your time and make sure you are accurate and follow whatever guidelines are set (depends on your role) you will get faster with practice ....they can and will deactivate you for not meeting their standards, and there is no second chance.
The other thing is payment. I believe to get their once a month direct deposit, you now need to have $150 earned, or you wait until the next month....there is no set deposit month, you will not get it until you have earned that $150. Otherwise, the other option is a debit card (I think that's still the case, never used it) but they charge a fee to deposit money in the account, it used to be $2/transaction, which could be an hour of your time.
I would not work for them unless a few dollars really made a big difference to you, and you absolutely have to work on a no schedule, no phone, at home job.
ETA: They also will not handle your taxes for you, so you will owe on your earnings come tax time...
