This is going to be a long hard slog. Steps:
a. identify ingrediant list, develop formulas...will cost 20,000 or more to get approvals
b. source materials, distributors
c. source packaging
d. hire marketing and product design specialists
e. enter production
f. locate distribution channels
g. house inventory
Expect to invest about $100,000 or so to get off the ground. You need partner investors. You need someone to get you through the regulatory red tape. You have to pitch your line to distributors and see if they will offer you shelf space. You will need to advertise your product and promote it.
Sure you want to do this?
