A family that is considering you sends a link that previews as A few questions from the family's first name. The page asks what you can do, which schedules you could fill, your phone, whether you are open to a background check, three references (or whether you would list them once they decide) and your proposed rate. It shows the care tasks and schedules the family needs and nothing about the patient — no name, no address, no record.
The family accepts, proposes a different rate (you can accept the counter or propose again) or declines. Accepting sends you the same invite the family uses to add anyone to their home team, with the agreed rate.
