Generally I personally avoid free work. It just doesn't pay.  Even so you do need a certain level of trust to do paying work for someone online. I think you need patience. Snail mail is slow and you must wait for that on occasion for payment. I think it is better to go thru a third party most of the time like here at rosity or turbosquid or Daz. If you do free work do it for someone you know personally make up a fair exchange. I swapped a monster model for a building  and that worked out.

I cheated on my metaphysics exam by looking into the soul of the person next to me.
