As far as I know CAA have scrapped the P2 rating. It's either P1 or bust....check with them first before you pay anyone for a P2 rating. Try FedAir or get hold of Grahame Woodhouse who is a DE thru one of the Virginia training schools and see if he can help....also try AvStar.
Sticky situation....odd that your prospective company can't organise as they must have instructors for line / prof checks.
