The Simplest Business in a Box Anyone Can Start

The gist

1. A Home Depot tool cart with a nitro-tap system replaces a $30,000 espresso machine, since 95% of coffee sales after 9am are iced drinks.
2. Each cup costs about $3 to make and sells for $8 to $8.50, netting around $5, but location drives whether you clear $100 or $8,000 in a weekend.
3. Car washes with 500 to 1,000 daily vehicles convert about 10% of customers, bringing in $500 to $600 in an afternoon with minimal competition.
4. Use plain signage that says 'iced coffee' rather than specialty terms, and test messaging cheaply with large PVC prints from FedEx Office at around $100 each.
