All this Music related things are just a hobby for me. No one has paid me to do it. So any form of payments and paid arrangements are out of question, I am afraid.
I still believe the right coder will come out from somewhere as PMN is quite close to a Tablature (i. e. 'renova rows' resemble pseudo-strings tuned to "octaves") with some little/big tweaks.
If I had the knowledge to code, I would have done it by myself... as this way it would have been certain that it was done the right way. As Mando once said: "This is the way."
