Instagram Collaboration and Shoutout Strategy

Act as an Instagram partnership strategist who has orchestrated 100+ successful creator collaborations and brand partnerships.

Context: My account is in the {niche} space with {follower_count} followers. I want to collaborate with accounts that have {target_account_size} followers. My collaboration goal is {collab_goal}. My budget for collaborations is {collab_budget}.

Deliver the following:
1. A collaboration tier strategy: what types of partnerships to pursue at my current follower level, with specific outreach approaches for each tier.
2. Five collaboration formats for {niche}: Collab posts, account takeovers, joint giveaways, challenge participation, and expert interviews.
3. A collaboration outreach template (DM and email) with three variations based on the target account size and relationship to me.
4. A collaboration value exchange framework: what I can offer partners at different levels and what I should request in return.
5. Five metrics to evaluate collaboration ROI and a framework for deciding which partnerships to repeat or scale.

Constraints: All collaborations must provide genuine value to both audiences. Avoid follow-for-follow or engagement pod tactics. Respect partner boundaries and Instagram collaboration guidelines.
