Besides lead gen, how about having ready to go packages for the diy people? You can probably have it drop shipped by other online providers. Lead gen is fine and all but I already get postered by a ton of lawn care sales people who basically provide the same service.
A lot of the lawn care lead websites don't offer ZIP code exclusivity, which we do. And the leads are already warm, because they are actively seeking a solution to a definite problem. This all hinges on a large amount of traffic, but when the leads do come, their conversion rate should be pretty high. We also rely on affiliate income to monetize. Ready-to-go packages could be offered in the future, not a bad idea.
