Amazon was the first place I looked! They have lots of netting but it appears to be tubes of material, like a sausage wrapper. I’m not sure what sizes would work for what cuts of meat. I could probably bum a bit from a butcher but I’m looking for something I can get in bulk and sort of standardize my method. Bear in mind that I’m a chef, and if I get this spec’d out right I will eventually start doing it in a restaurant setting.
