The wedding planner we had came with the actual place we had the wedding. She did everything for us, from food, to drinks, to having a tasting day where we could sample all the caterers they did business with, to florists. All of it. It was awesome but I know places that are all-inclusive are hard to find. She wasn't very pushy either with anything but maybe we were lucky in that respect. Here is the place we dealt with:
