I wanna keep my puppies:(?

I have four little Maltese puppies who are about 10 weeks old. I have handraised them from when they were about 2 weeks old after the mum was backed over in our driveway (by my cousin whom I still won't talk to) I watched them being born and was with their mum throughout labor and the birth. But I know have this attachment to all the puppies and my hubby has told me a couple weeks ago to start advertising them for sale. But I have not done it.. Because I love them like my kids and they are so beautiful and they get so excited when they see me and all snuggle up to me whenever I sit down :) my sister told me that they gotta go sometime and how it's nuts to wanna keep all of them but I really do love them. And I don't wanna sell them:( I would rather give them to loving homes than sell them. But when my hubby does eventually make me give them up how do I know what to look for in a good family? And I wouldn't be able to keep just one cause I'd feel too guilty:(
