I would pay for this, and I'd be willing to pay something approaching professional fees for individual attention, followed by a maintenance/insurance fee like you describe.
Things I'd need (as someone protected by GDPR):
1. strong privacy guarantees on your side
2. transparency about the process and techniques used
3. regular feedback
4. attention to data brokers, but also to anywhere else my pii might be on the internet, which could include shutting down e.g. old accounts on random shops
5. visibility into hacked data dumps (like haveibeenpwned, but for arbitrary information)
I'm pretty sure my information is spread all over at this point, but I'd like to get a handle on how big that spread is and to contain it wherever possible. I'd like to have an idea of how hard it would be for someone with some partial info e.g. a phone number, to determine my name or address.
This kind of service is something that I'm looking for now. I suspect that something like this already exists in "reputation management".
