Its a whole lot of labor spreading all that compost. It would take about a tenth of the time to apply organic fertilizer like Milorganite. Better yet, Barry can fix you up with some Screamin' Green; see Phasthound. You could follow up with grass seed--as it is easy and quick to spread. Top-quality seed is darker green and much thicker.
You should not apply lime without a soil test--or at least a pH meter reading. I have oak trees in my yard. Oak trees do not cause acid soil. Michigan soils in my area are only slightly acid. Lime is seldom recommended.
We don't need more competition--but it would be a lot better to get your spray license--weeds cause a lot of customer dissatisfaction.
