Plumbing Membership Plan Drafter

Produce a complete, shop-specific membership / maintenance plan package — tiered structure, pricing logic, included services, fine print, customer-facing one-pager, sell-in scripts for techs at the kitchen table, renewal messaging, and upgrade paths from one tier to the next. The goal is to give a plumbing shop owner the entire "here is our membership program" asset bundle in a single pass, so the shop can go from "we should probably have a membership plan" to "here is the plan, here is how we describe it, here is how the technician offers it on the last 90 seconds of a service call, and here is how we renew people in month 11" in one afternoon.
