We have just become my boyfriend's grandmother's caregivers. Where do we begin?

We have just become my boyfriend's grandmother's caregivers. My boyfriend and I live with her in his parent's house. His mom just recently passed away (his father passed away 2 years ago). His mother had been the grandmother's primary caregiver, staying home with her most times (mom didn't work- disabled). We are both in our 20s, and we have been doing well this first week after his mom's death- but we are going to need help soon! We both have to work full time, and I'm going back to school as well at the end of the month. I've started researching elder day care facilities, etc. I guess I just need some ideas of where else to start- home caregivers etc. Thanks!
