I think you should first dive deep to know what is your main field of interest. you have a skillset that covers wide variety of jobs and gigs. you need to be more specialized in order to know what is your niche. even if you applied to do a “free gig” for a company, they will ask you what is your concentration and what is your previous experiences that should ofcourse be relatable. working some part in programming and other in digital marketing will not be relible for a business owner.
I suggest you:
discover your perfect niche
Search for companies and businesses in that niche
Search them for internships and voluntary work (use Linkedin, indeed, …etc)
Wish you all the best

I think it needs to be more visual, I suggest you make the “churn story” in the form of comic book with each stage (heading like: Churn happens, Catch them…etc) to be included in a block (web designers will understand) with an image representing it. make it a funny let’s say “Churn happens” block to include the image of a minion moving out leaving an open door. “Catch them …” block, another image of a minion running after another to catch 😂, and so on. My main idea mak it visual and appealing. wish you all the best.
