Hello,

there are sites which provide free lancing jobs. there are projects you have to complete and each  of it has a particular target time and money to give after completion.

You can look for one as per your interests and get the job done as per your suitable time and get the money. You have to complete it within target time else you may not get the money. If you want some break then leave taking projects. after completion of your break you can join again and take projects.

Hope it helps!
