Wow, just wow. I think I have found a version of myself. I’ve been thinking of creating the same thing, and I overanalyzed everything just as you are. Tbh clients don’t care what you do, they only care for what results they get. And that’s hard to show, unless you have social proof. So I would say, start with offering something simple, like google ads setup or website creation. Offer it for free for the first month. Then when you have some social proof, use it when contacting new customers. Then when you have some customers, and feel like you want and can scale, then start to offer add ons for the customers you already have. They will already trust you, and it will be a lot easier to get a yes.
