Feedback please - Productized media agency

Hi all, I need validation, please.

I've been building a social-first media agency that provides content creation services for brand building and business growth through social media platforms.

We use a combination of the Design Sprint + Growth Hacking methodologies, applied to social-first content creation.

Through our website, people may buy one of the three packages:

Strategy plan - contemplates market research, competitors analysis, branding strategy (tone of voice, positioning, etc) and content strategy up to 3 social media - delivered over 2 weeks.

Execution plan - contemplates all things in the "Strategy plan" + Roadmap, Activities planning, KPIs file, and templates to create social-first content at scale for 3 social media platforms - delivered over 6 weeks.

Implementation plan - contemplates all things in the "Strategy plan" + "Execution plan" + creation of social-first content, campaign management, testing, and final report - delivered over 3 months.

Please give me feedback on the value proposition and our Plans

Does this create any value for you? If not, what would create?
More social media platforms? More content creation?

PS:
What do I mean with social-first content creation? All sorts of content that is social media native and easily shareable through social media.

Which sorts of content do we create? Mostly design at the moment as: Carousel posts, E-books covers, Facebook and LinkedIn covers and posts, InstaStories and Insta Stickers.
