Question for Gema Home Stay

Hai... I'm syeri from Malaysia. I'm a student from Universiti Malaysia Sarawak. We will have a visit to Bukittinggi in August for some social work and knowledge sharing with nearby university. The exact date has not been decided yet. There will be 15 of us mix of men and women from age 22 to 50. We wish that we can rent your homestay for 2 nights. Can I know the price for 2 night at your homestay?
Thank you ☺
