Ask HN: (looking advice) building websites for local businesses (Side hustle)?

I work with Java and at the moment looking for new job. In the meantime I’d like to work on some side hustle and have read some people here telling about creating websites for local businesses and maintaining them.

My idea is to cold call/email local businesses in London (where I live) that have very old website and offer them a new one page website, easy to build and maintain.

What kind of hosting would you recommend for one page websites and suggestions on how to monetise other than one-off?
