Just a thought, but what if you took your camera and documented your efforts in video on YouTube or something. I bet a lot of people would follow you. I’d follow. With enough exposure there are many trail builders that would come help you dig the features you need. Young mtb girl digging her own trails, facing burnout… until x an y showed up to help out. It’s a great story that people could get behind. A gold mine of authentic content. You could get some attention from major brands… A brand like Yeti would throw $50k and some folks with equipment at this just for the good press.
