If you want to see the vast expanse of DIY dollies, jibs, lighting, costuming & make-up tips, I recommend a web search. I know of several sites I found useful, but I don’t recall their names or where the print-outs are now. But try “guerrilla film making” or “guerrilla lighting” including the quotes, and you can surf around to the sites that speak to you. I’ve seen articles on making reflector umbrellas, ways to gel work lights and over the door light mounts.
Good luck & enjoy the hunt.
