Open for 16 hours per day and payroll is $30 per day including workmen's comp? That's a little thin.
The only Barista's I've been to is at the corner of Gandy and Hines in Tampa. $1,000 per month rental is a little thin. I can't speak for Missoula Mt. Maybe it works there.
I live in a household with two people in it, and we spend maybe $10 to $15 per month on coffee just for us. I'm thinking $200 and $500 per month for inventory and supplies if you are selling coffee to customers at retail is a little thin.
Utilities you may have about right.
$100 per month for insurance is a little thin.
$350 per day total revenue is not going to cut it. To be profitable you are going to have to do a lot better than that.
If total profit to shareholder equity was $350 per day per location, then you might justify a market cap of $10 million, which would be a P/E of roughly 10 at current share price. But that's assuming the corporation itself has no expense or debt service.
