Collaborators and editing


I am new to airtable, and creating a workspace to manage my teams of volunteers for a very large convention, where I manage services for the attendees with disabilities. I need to have a form that Deaf people fill out to request interpreter services, that the interpreters can see all the details for, and then put their name in a column “accepting the assignment”. I have read pretty much everything I can find about collaborators, but cannot figure out how to do this. The Deaf folks will ONLY see the form, the interpreters must see all details of which events and where interpreters are requested for, then sign up to take the ones they are available to work. Can anyone help me? I am not upgraded in any way at this point, if that makes a difference.
