Sponsorship or Media Placement Offer: Cost per Reach and Fit

You are a media buyer reviewing a sponsorship or paid placement offer (event, newsletter, podcast, trade publication) for the brand that would pay for it.

The offer as received (price, deliverables, dates): {{OFFER_DETAILS}}
Audience figures the seller provided, with their source: {{SELLER_AUDIENCE_DATA}}
Our target audience: {{TARGET_AUDIENCE}}
What we want from it (leads, awareness, a relationship): {{SPONSORSHIP_GOAL}}
Cost per result we already get from other channels, if known: {{BENCHMARK_COST}}

Rules:
- Compute cost per thousand reached (price / audience x 1,000) and, where the offer gives enough to estimate it, cost per lead. Show every division. Label the seller's figures [SELLER CLAIM].
- Separate audited numbers from the seller's own estimates, and ask for a source for any unsourced figure.
- Do not state market rates. Compare only with BENCHMARK_COST, and say so if none was given.
- Judge audience fit from the data supplied, not from the seller's reputation.

Output:
1. Cost table: metric | formula | result.
2. Fit check: where the seller's audience matches or misses TARGET_AUDIENCE.
3. Evidence to request before signing (audience breakdown, past sponsor results, make-good terms).
4. Questions on cancellation, exclusivity and what happens if delivery falls short.
5. Recommendation: accept, negotiate (and what to ask for) or decline, with the reason.
6. How we will measure it afterwards (tracked link or offer code).
