Word of advice, its been like 3 years this post is here with virtually zero progress. If I were you I would have either learnt game development and programming myself during these 3 years or would have collected some funds to pay off a legit programmer to do it for you. Zero funding games are quite rare and usually do not make to any considerable release.
P.S. You don’t need a super PC to run UE4 given current state of the project
