Ask HN: How to provide a hands on service to local businesses

I just handed in my notice and I'm wondering how to supplement my income as I grow my sideline. I like the idea of providing a hands on service to local businesses which is meaningful to the business but does not require a lot of my time (possibly on a monthly subscription). Is anyone doing such a thing? I am in Ireland so it's unlikely I will be muscling in on your work :-) Send me a message if you prefer.

My background is in infrastructure but I have also been paid to create websites and apps.
