Photoshop three photos into one & filter removal

I need someone to remove the snapchat filter from the girl and then edit both pictures onto a third picture (will attach this photo to a message once I accept your proposal) of a couple together. In short, I need the faces of both people in the separate images edited onto the bodies of a couple in one photo. All photos, once edited together, need to look realistic with the same lighting/photo quality. Timeframe: ideally need this completed within a few hours but willing to compromise.
