Group tour companies in Bohol that go to Philippine Tarsier sanctuary?

I'll be in Bohol (staying near Alona Beach area) for 5 nights in February.

I'd really like to have a chance of seeing the Tarziers and supporting conservation but I want to do it as ethically as possible. I'm looking for a join in group tour that includes the Philippine Tarzier sanctuary in Corella specifically as that looks to be the most ethical. There are a lot of tour companies but they all seem to go to the Tarsier conservation area in Bilar which is not ethical. Some even use the word sanctuary so I think it's the Corella one but when I look further or ask them it's the Bilar one.

Cost isn't an issue so I would be willing to get a private tour/hire a driver if I need to. I'd prefer a group tour though for safety reasons (solo female traveler) and because I'm introverted and don't like the pressure to interact constantly when it's a smaller group or just me.

Does anyone know of any companies that include the sanctuary or have any recommendation for private tours/drivers in the Bohol/Panglao area?
