I did something similar to it, calculated hom much time I would need to achieve the breakeven, marketing and media budget... But at the end is just a excel spreadsheet. I was wondering if I should establish a indicator (like growth rate, revenue, etc) and just after achieve this number take the decision. Or maybe contract someone to do this sales and marketing stuff and wait until the company makes money.
