David, you need to provide at least the information that you have for others to assist you. If you provide LESS than all that you know, then you should expect us to have LESS success than you have had.
If these people have profiles, then set them to have a public bio and populate them with everything you know that is relevant - and edit your question to link to them ! There are lots of people here that are keen to help but they need to know at least what you do.
The one profile you have mentioned is private!
