Call your training department, they have the paper that lists your last PC with all the "Acceptable" or "Pass" markers. Its a standard document that all airlines have, you just dont see it, we just do our PC and head home, they generate that document automatically.
Print your last 3 pages of your logbook. Start with your Chief pilot, ask him if he can sign them, if not then ask your base manager, if not keep going up the ladder until somebody does.
Not sure if they asked for it or not, but go ahead and call your local FSDO office and get the letter that says you're clean of incidents/accidents, you'll need it.
Hope this helps.
