No the co-host function, where you could look for a co-host via Airbnb is no longer running.
If you want to set up a company offering commercial services, you need to make sure you have the right insurance in place.
Airbnb does not offer insurance it has a 'guarantee' for hosts who want to claim for guest damage.
You also need to be very familiar with how Airbnb works so you can offer your client the best possible advice, keeping up to date with Airbnb's fast changing T&Cs.
Have a look at the Airbnb Help Centre it shows you how co-hosting works and how payments can be set up.
You will also need to have a proper contract drawn up covering what you offer, payment terms, T&Cs etc.
