Hand expressing breast milk

Anyone do this? I was exclusively pumping at first when my daughter was born but wic let me use one of their pumps only for a month. So I started letting them help me with getting my baby to latch and it worked! So I started breastfeeding but now all of a sudden she acts like she doesn’t want to latch after latching for a while. I supplement with formula. I don’t have a breast pump because I’m not working right now from my leave I took 10 weeks and they are expensive. I was thinking about hand expressing but it seems like it will take so long. Anyone who does this can you share your experience?
