Should I pump or not?

I'm 36 weeks pregnant with my first and after researching extensively I've decided to breastfeed my baby. However, I'm going to be running a daycare and watching kids as well and I'm just wondering if some other mothers who have done this before can give me opinions on whether or not I should pump breastmilk or not. My fiance wants to be part of the process eventually but he says he understands if I breastfeed exclusively. I'm just wondering if I should go ahead and buy a pump and then introduce the bottle after the recommended 3 months or if I should even bother with the pump since I'll be at home with the baby. Thanks for any advice in advance.
