adsense earning 15-20$ per day

Hi, i have 9 websites and i want that each site will earn 15-20 USD per day. if it is not possible on my old site then you can built a new website looking to work with serious people for a long term. If all goes well, this is just the start up, we will need in average 2 websites per month. only white hat technology will be used. complete payment will be issue after getting the desired position. DONT ASK ANY MONEY BEFORE THE PROJECT. DONT BID IF YOU WANT MONEY BEFORE STARING THE PROJECT.
