Help Building a Three wheel bike

I am trying to turn a 10 speed into a three wheeler for my friend. He has trouble riding a 2 wheeler. Does anyone know how to make one. He would buy one but cost is too high.

Make the 2 wheels in the front. Making it in the back would be much harder

My mom wants to do this. I can think of some sort of wheel and axle design where the chain part is attached to a bar with the two wheels each end and it would rotate where the one wheel used to be. I'll make a schematic later, need to examine a bike first.
