Water taxi ishigaki/Taketomi

Hi there, I am travelling to Ishigaki in June. We are staying on Taketomi for a few days. We have a flight from Ishigaki to Taiwan but the flight leaves sufficiently early that I wouldn't want to risk relying on the public ferry from Taketomi to Ishigaki. I'm therefore looking for someone who could do a water taxi for us instead – grateful if anyone has any recommendations or experience of this.
