I've called all businesses in my country for a certain industry.

I want to start to acquire businesses for other industries. How do i accelerate the cold calling process.?

I'm hiring someone to come to my house and do cold calls with me.

Is this good or bad? What should i look out for? How do i build an M&A team that can PUMP through deals all day and sift through them so i can buy businesses on a MASS scale.?
