Any thoughts on this gameplan selling GHL automation services?

I’d like to know if this sales gameplan would work.
Step one: Pitch review automation service to local businesses, preferably ones that take online orders that require some kind of email or phone number exchange to take place. Like a restaurant, or tailor.
Step 2: If the previous step works, and a relationship has been successful built, pitch a website form integration of some kind, depending on their service.
Step 2.5: Similarly to the other step, pitch an Ai phone system service depending on what the business sells.

The review system is an easy way for businesses to tighten things up, so I would automate their google business profiles so they go from 50-100 reviews to over a thousand within a few months. I could probably even let them try it for free for the first month or two, although the most I would charge is 50 or so dollars a month.
But it’s mainly to build trust and the relationship, which I could then use to pitch the heavy duty services, like the AI phone system, or maybe an email marketing service. The way I see it, it’s borderline impossible to pitch a service that a business owner doesn’t understand. The far more likely solution is to just do something for them that provides immediate solutions for relatively cheap, and then show them how the other stuff works after.
Does anyone have any critiques of this plan? If you have any advice or criticism, I’m all ears. I’m probably going to put my head down for the next 3-6 months while trying this, I already have a few clients I’m working on this for.
