Startup costs are estimates, typically around $2,000 to $7,000, depending on how much stock you buy, event fees and the equipment you need to display and deliver products.

Monthly revenue is an estimate, typically around $800 to $4,000, depending on how many events you attend, your trade customers and your product mix. These figures are revenue before your costs.
