Engineering is not about having money, but an organized plan for the material and principles at play. Even non-functioning off-scale models and drawings of fantastic nature and shitty proportion creates understanding, raises more questions for the next iteration and is the beginning part of any plan. In fact if those are not done, it would not be engineering but money fraud because risk is not assessed and potential is over blown. It will be a pure waste of material, labor and capital.
Project your mental image into the physical world if you love it so much. Melt wax, shave wood, fold paper, drill pipe, bind sand, hotglue boxes, do whatever it takes to express the idea. Doing things yourself cuts down on complexity as stuff you see on media but not made available to you is simply ignored and starts looking on what you can have.
Start organizing your thoughts. No one else can. Try writing on different kind of paper and bind them. Paper clip with cardstock and 3 hole punched paper with binder are my favorites.
