it's not easy to earn that much online, You can't get that much just from faucets and need a senior or more account to earn it online, If you have some skills like coding, designing and the like making it is possible but otherwise it would be very difficult.
I don't think that senior or even Hero accounts can't make this amount by week only using the actual signature campaigns, we know the actual payment rates for the signature campaigns and even the Hero can't make 0.3 BTC weekly with this rates.
