Honey, if you're just gonna get rid of her, why would you bond with her?
If you're gonna bond with her, how can you say that you're just gonna sell her? What a sad puppy dog...
If I were you, I would either make the decision to be this dog's life companion, or find her one before you breed her. First off, you won't make much if anything off the pups, she could die, the pups could die, it's a spendy hobby, as well as a stressful one. No, I'm not a breeder, but I want to be someday, and have been doing lots of research.
ANYWAYS...about the peeing...If it's when you get home and stuff, don't make a big deal out of coming or going. Try just to not make anything a big deal at all. We went through this with Joey, and he's now fine. He rarely pees out of excitement. She could also be doing it out of stress. She's in a brand new house with new people, and she's probably stressed, confused, and sad that she's not with her old family. I wish you (and her!) the best of luck.
