Hi Brian,
You might try a Witches Bottle. Obtain a moderate-sized bottle (you'll see why the size matters in a moment), fill it with as many sharp, pointed things as you can find, e.g. razor blades, shards of glass, needles, etc. and the fill it with urine (yours of course) and bury it in the woods where no one is likely to ever find it. That should do it. Lady Mimi may also suggest any number of items/spell-kits which do some or all of this. Consider giving her a call for more personal advice on choosing one of her products.
