New Mom Pumping

Hi, I’m a new mom (3 months postpartum). I recently started looking for jobs and putting in applications. I have an interview Tuesday. I’ll be working part time hours. I exclusively breastfeed. I have a breastpump I got through insurance. It’s the Medela pump in style. I tried using it before, it pumps extremely slowly. It doesn’t fit right. I need to start pumping for my husband; he’ll be with our daughter when I’m at work. But I just don’t have time to sit down for hours to try and pump multiple bags and bottles. Do I need to build up my supply, get a better pump, or something?
