15 years worth of postholes is 200 * 365 * 20 = 1,460,000 postholes, that would mean a profit of $0.0136 per posthole. 6 months worth of postholes is 200 * 30

15 years worth of postholes is 200 * 365 * 20 = 1,460,000 postholes, that would mean a profit of $0.0136 per posthole.
6 months worth of postholes is 200 * 30 * 6 = 36,000 postholes and a profit of $0.55 per posthole to pay down the capital investment.
In my original post I claim $5 per posthole profit can pay this off in 11 days.
