I formed my LLC back in the mid-nineties. Very little was required: 2 computers, 2 desks, a filing cabinet, a printer, a fax machine, business cards, some office supplies and advertising literature. It still cost me near 20K. With inflation 50K would not be unreasonable especially if you are buying lab equipment. I ran it out of a spare bedroom of my house. Being undercapitalized is almost a guarantee for failure.
