Please advise: Airport transfer needed Osaka - Kyo

Dear members,

I am looking for an airport transfer from Osaka airport to a hotel in Kyoto for ca. 24 people (including my mum :)). They do not necessarily have to travel together. Separate cars are also ok, even though one bus is preferred. Could you, please, let me know what could be approx. cost? And if you have any contacts you could recommend, will be highly appreciated!

Thanks a lot!

Margarita
