In all honesty you would be best learning programming yourself or perhaps start another project as this one is not getting the interest you are hoping for. Otherwise You will most likely still be here in 5 maybe ten years lol, recruiting for people that will most likely never come.
There is definitely no decent Royalty or Unpaid willing programmers that will do it justice. You would need to source some funding and offer some paid tasks to try move forward.
but like said above best to learn the programming yourself if you really want to stick with that game / design…
anyways best of luck…
