Searching for a Costume around $500 - $1000


With moving mandibles? That's animatronics you're asking for and that's going to push into the $5-8k department.
Man, that looks very nice. Do you have a website i can check out? Do you sell masks with moving jaws?
There may still be tutorials out there for a guy years and years ago that did a form of these. He went by the name GRUSDERK. Try googling GRUSDERK predator mask. It was pushing 10years ago but I made one based off of his ideas that was quite doable on a lower budget.
