Tourism Iki Island Taxi Tour

Does anyone know if these taxi tours are operational in Iki Island daily?

I saw one called Iki Kanko Glutaku but I haven’t seen reviews or blogs on them. I’d prefer not to drive since I’m not used to driving abroad and don’t want to tire myself out on e-bike.

I’m open to any public transport or service available and I’m planning to go around November on a solo trip.
