I guess in your game there would be a ton of elf’n’safety and procurement hoops to jump through.
But if you have a solid business plan and cash flow projections and back yourself then go for it.
I’m not an expert by any means and with my business people are basically paying for skills and knowledge (I do marketing strategy, campaign management, some creative work and digital advertising) so my outgoings are tiny.
Subcontracting is a small part of what I do but it’s basically free money. Last month for example I had to get some video editing done. Charged the client X and paid my subcontractor Y and pocketed the difference - nice bit of cash for sending a few emails. Everyone was happy.
