I want to make a Springtrap/Springbonnie suit but I am utterly lost

As the title says I want to make a Springtrap (Springbonnie if Springtrap is impossible) for the fnaf 3 movie whenever that comes out. My current best lead is How to Make a Springtrap Costume - ON A BUDGET! and as that video says I am on a huge budget (my country is in a 7 year hyperinflation streak type of budget) with all this said, I am looking for more guides on Springtrap costumes (better looking mostly though I hardly think anything better looking would cost less than a kidney) and definitely at least one budget Springbonnie costume. Anyone that can help? Thank you!
