based on a very quick research on conversion rates - 15% is an optimistic rate.
this equates to 600x30x15%=2700;
2700x1.50(company figure /customer)=$4050/month
extrapolated over a year say average
15000x1.50=$22500x12=$270,000.
Annualised revenue=270000
Annual costs =(900000)
loss =(630,000)
It all depends on conversion rates, obviously, considering a market of 500000 million, trial rates seem poor. Interseting to see march figures.
