Do this to get leads for your service

You want to script out videos and do the editing for people? It's like, okay, well, like show me some edits. Oh, I've never edited a video before. It's like, What do you mean? It doesn't make any sense. If you're trying to sell YouTube editing as a service, you make content related to that and try to produce clients and leads from YouTube.

If you're trying to get leads for your business and do lead generation to get clients, doesn't it make sense to actually do the thing you're selling?
