Identifying Sites that Need Help in My Area

[pranaman]

I'd like to find sites that are either old, not mobile friendly, have been made with simple builders, like godaddy's, weebly, wix, squarespace, etc, and that their owners are close to me, here in San Francisco.

Also, distinguish ones that have an email vs ones that don't and have a contact forms, with or without captchas.


Ideally, generate a list and their owners so I can contact them for work, to either updates, upgrades, redo their site, etc.

What I don't know is:

What is the best way to sites with the above information, within ~ a 5 mile radius of the center of San Francisco?

How can I get a sense of how many sites there are - 10,000? 100,000? 1,000,000? more?

How can I go about finding more, to ultimately create a report with the above information, separating site records with emails, which are easier to contact, vs ones with contact forms, which would be harder to contact?

There's only one reason that i can think of to generate such a report, and it ain't a good one.
