How Can I Produce More Breastmilk?

I’m pumping and feeding breast milk and supplementing with formula.
I’m pumping every 2 hours. I pump till nothing comes out and I’m only getting about 3/4ounces each time.
Is there a way to produce more? I want to be able to feed only breast milk but right now I’m not getting nearly enough.
He’s a week old today (wow!)
Thanks
