Did some research you have on your website you need 250,000 to start your own private small buisness. Here's the SIBR.gov who will give you almost a guranteed grant for your buisness and their requirments for your funding. I would suggest you select educational because you're creating props for movies and for hobbyist and also it's also a college degree. It's listed under any college education section under Theatre Arts: Prop Making & Special Effects <-------------------. Attached below is the link so you can get your funding. Enjoy and Merry earily Xmas.
