Yes—both.One-off projects: Fixed scope, fixed fee, and a clear timeline with milestone check-ins (outline, first draft, final). Ideal for patient education materials, health innovation content, and scientific manuscripts.Monthly retainer: Reserved capacity for ongoing needs (e.g., articles/newsletters, iterative manuscript edits, multi-asset campaigns). You get priority scheduling, faster turnarounds, and predictable budgeting.Typical setupFor one-off projects: I send a scoped proposal with a fixed fee and timeline after a short discovery call. Payment follows a 30/40/30 schedule—30% at acceptance (to reserve the slot), 40% at first full draft, and 30% at final delivery. The fee includes an outline, a full draft, and 1–2 revision rounds. Out-of-scope changes are quoted separately, invoices are Net 30, and you own the final work upon final payment.Retainer: monthly fee tied to agreed outputs or hours, simple rollover limits, cancel anytime with 30-day notice.
