Having a media kit has landed me partnerships with brands. They are a must for higher paying collabs! But I would suggest keeping your rate card separate.

@Michel Guntern The majority of collaborations I've done have been with tourism boards, but I've also worked with a few brands, including Newell Outdoors, ROI Recreation, and BC Wine Growers. I'm currently in talks with a hotel for content creation right now. I am a travel writer first, content creator second, so I'll often offer my Influencer/content creation services in conjunction with a media trip for traditional media coverage.
