>>69411897honestly? depends on what you and yours can do.
you can technically start one with 2-3 talents (no point in a corpo if only 1 talent).
its getting the model and rigging thats the expenses, + cost of securing the company name and such legally.
you probably want custom backdrops and such, but in reality you could cheap out on them.
so really, cost of 2-3 models and rigging.
learn to do both of those yourself and you cut down your costs to be absurdly cheap all things said.
