Question about Kairos University and Doctoral programs

This is my first post here so I am not sure if this is the right place for this but here I go. I am looking into doctoral programs at the moment. I am looking at a few Universities in the UK. I am also looking at some schools here in the US. One school I have applied to and been accepted to is Kairos University. Their ThD program has a faculty assigned by the school. However, they also require the student to recruit two additional academic mentors. They do not have to be people with formal education. They just need to be experts in the subject. Which for me is Patristics. I have been told that I will not be able to complete, or even really start, the program without all three mentors. These two additional mentors are not compensated by the school. The school even claims that many mentors refused to accept payment when they were offering it. I have found the opposite. That many people who have that expertise would like compensation for their time. They are ATS accredited and I do think their format has some real potential. However, I have some concerns about them requiring outside, unpaid support from whatever they define as an expert. Do you believe that this is acceptable? I am working on other programs and hoping to get a scholarship. Thank you all for your help.
