@Jessica2651 There might be a very small niche out there of people who want to use services like yours, but it's not a searchable amenity on Airbnb. So it would be an extraordinary coincidence if a guest who wanted to rent a house with a personal chef just happened to click on a listing that offered one.
Still, there is another thing you can do: create an Experience listing and host a culinary activity. You don't have to offer overnight accommodation to teach a cooking class, lead a foodie tour, or host a dining experience in your own home. Airbnb promotes its Experience listings to guests who book accommodations in your area, so it's not necessary to partner with individual hosts.
