If she’s even real (could be a troll account), we have no idea what she’s talking about. Quick half hour or shorter shoot for your family after getting a new baby? A wedding lasting hell, maybe 5-6 hours or more? 300 bucks is way too much for the first option (assuming she has a studio and can just shoot 1.5 families an hour and then do the editing later) and probably about a fifth of what the second option should cost.
