Puppy left alone for 3-4 hours

Hello I have been wanting a puppy for so long now and I’m so close to doing it. I am single and work from from Monday-Saturday so I will be home with him/her almost 24/7. However on once a week usually on Sundays I do have a part time job that requires me to be away for around 3-4 hours usually from 6pm-10pm. That is the only thing holding me back. I do live alone but also less than 10 minutes away from my parents however they are in their late 70’s and don’t want to put that on them. Any advice will be greatly appreciated, thank you!
