Remote usability testing with disabled people

Hello,

I launched,  Inclusight <http://www.inclu-sight/>, a startup that provides
disabled participants for user testings. After providing for a while,
disabled participants for face-to-face user testing, I figured out this was
not the best solution. It's not convenient at all for disabled people as
they need to travel and to plan the session a long time in advance. And
when they start the testing, they figure out they cannot use their own
familiar configurations. It's also a pain for user researchers who, on top
of that, are not always aware of how is it to work with disabled people.
That's how I came up with the ambition of offering remote usability
testings for disabled people. At this stage, I am looking for professionals
willing to share with me their experience in doing remote user testing with
vulnerable or disabled people. I want to understand how you could make the
most benefit from Inclusight.
I am looking forward to hearing from user researchers, web accessibility
experts or any other professionals.
Kind Regards,
