Well you need to learn editing however you will know jumping to the toys is as much a mistake as building a dedicated workstation with lots of screens as a first step in trading.
It starts with storytelling then scriptwriting, then visual storytelling which is using shots, cameras, sound and lighting etc. Editing is not difficult once you have the first part. Without the script saying no more and no less than needed which frankly, you struggle with, editing won't fix it. Licencing music, Pitching and marketing are of course crucial. Mad Men stuff.
A good approach is to make uncomissioned ads for existing products, they can be quite viral but watch the legals with the major corps like Coca-Cola who may crush anything with prejudice. Midrange to small but familiar is best. If they go viral, you might have a shot. But don't only think obviously tangible products, also services, insurance, law etc. You must understand that green field is rare, you have to adapt to the customer's ideas.
I'd strongly suggest you be cognisant of how tight the margins are these days. It's a competitive area for digital nomads and film students. But this is also a way to get footage to work with.
