Did you try CAE or PanAm Academy? They do type ratings on the A320 so I guess you can rent the sim and do your ATP check ride. I know that CAE accept to rent their A320 sim in Toronto for 475$/h, maybe they have a contact with FAA examiners.
I am looking for a F/O job or line training in Asia on the A320, I have the 320 rating but no experience on type. Could you please tell me in which airline you are flying and what are their minimum requirements?
Thanks
