Need Harry Potter OC Fanfiction!?

Harry Potter fanfiction that has oc's paired with canon people. Like Harry/Oc, Sirius/Oc, Remus/Oc, Bill/Oc, Charlie/Oc (very interested in Charlie now.) Nobody with oc pairings like Hermione and Ron have to be together or James and Lily have to be together. I'm a huge fan of Harry/OC and apparently Charlie/OC, but I can not find any more good ones to read about them. I've been looking on fanfiction.net. Any good sites?
