@Rodney157 It's not worthwhile for a caterer to enter a "partnership" with an individual rental unit serving only max 6 guests. Airbnb doesn't offer "private chef" as a searchable amenity, so the extremely small minority of guests who might be interested in that as a feature have no way to locate a listing that offers it. And caterers rely on having their services booked and paid well in advance by a reliable client, not summoned on a whim by a small group on holiday.
If you'd like to offer a daily breakfast delivery as an inclusive amenity to all your guests, that might be a level of consistency that would appeal to a service that specializes in this. But you'd have to partner with a restaurant that already has a breakfast service route in your area, as it's really not worthwhile for a private chef to get up early in the morning and make a personalized meal for 6 people at a beach house (at least not at rates that would keep your listing competitive).
Your listing is still very new, so I recommend keeping your focus squarely on maintaining the quality of the amenities that are already attracting guests. Giving personalized recommendations for other services is fine, but a "partnership" means your business takes the hit in a review when a guest isn't satisfied with a service that's out of your control, which basically slaughters a listing at your price point.
