Whiskey Old Fashioned Sour

What are some recommended mixers?
I'm getting married and the reception that we need to provide our own drinks. We will have beer, wine, soda and water. But then I'm going to have a small selection of liquors. I'll have whiskey, brandy, rum (Malibu and Bacardi probably) and vodka. Any suggestions on mixers that go well with a few different liquors? I have coke (can go with anything), tonic (for vodka and tonic), cranberry juice (With vodka), orange juice (with brandy or vodka), 50/50 or squirt (For things like sour whiskey sour or brandy) … any other suggestions for "must have" mixers? I'm thinking of tomato juice and mix well outdated. Then, I'll limes, olives, celery salt, Tabasco … something else?
