So I want to find a place to setup a bunch of btc miners, but my house does not have enough electricity.

 So I wanna find a place, I think something like "industrial where house" right? correct me if I'm wrong.

I live in Orange County, Cypress city, Southern California.

How many amp do I need if I'm serious about expanding more miners in the future.
How hard is it to find high power like 500amp plus for 1000 square-feet? Where do I go to find one? Does contacting a real estate agent help? Thank you so much in advance.
