Draft a monthly marketing retainer proposal from a freelance marketer to {client_business}, priced at {monthly_fee} per month for a {contract_length} engagement focused on {service_focus}. Structure: a two-sentence problem framing built around the client's own goals; a 'What you get every month' section as a bulleted deliverables list with exact quantities (e.g. 12 posts, 2 performance reports); a clearly fenced 'Not included — quoted separately' box to prevent scope creep; a simple 3-step onboarding timeline for the first 30 days; and a results-review clause at day 90. Keep it under 550 words in plain, confident English with no agency jargon, and write the deliverables so specifically that both sides could audit them at month's end.
