Fiverr. Gig for 5 dollars. Build up you reputation selling something that normally sells for $10, and you will get 2 order per day or more. Or price it $10 and deliver a value of $20, you get the idea..

If your objective is to simply make $10 remotely, with no other criteria, it's rather easy. Up to $80 dollars per day, if you are willing to do stuff for up to 12h each day is not that hard these days with service marketplaces.
