I've used the search widget and have come up with little in the way of conclusive discussions, so here we go. A few caveats: One is that rates vary geographically and demographically. Have to leave a fudge factor for that. The second is that the age of the operation may tell a lot about how many services an LCO has sold its regular customers: mature businesses have had more time to sell a higher percentage of customers more services. There are more, no doubt, but this is a good start. For an LCO offering mow/edge/trim/blow, fertilization, aeration/seeding, shrub trimming and fall clean-up on lawns running between 1/3 and 2/3 acre, assuming the average lot is about half an acre, how much revenue would you average per customer?
