I believe there is a tool out there that can convert an Xbox save to a PC save (I know there's a tool for PS4).
So, build each level of the plan and save each level. Transfer the saves to USB so that you can upload those files to OneDrive. Make said saves public and send link to whoever is willing to help you convert it to a PC save.

This is where I got idea.
Of course you wouldn't have all the same asset pool that the PC users have, but I think this could work.
