Switching over to exclusively pumping

I HATE pumping but I want my baby to have breast milk for as long as he can. Right now I’m able to pull off pumping every other feed of my baby’s (about 5-6 hours) and pump enough milk for two bottles (6-7oz). That’s good right? Has anyone been able to increase what they pump so that they’re really only having to pump a few times a day? Does this work? I’m so new to this. Lol. My goal is just to pump as much as I can in as few sittings as I can.
