Update:
Right when we dropped the car off to be jigged we waited 2 days then got a phone call saying the engine needed to come out and to do that, jig it and fit the engine would be 2k *faints*
SO we asked how much if we removed the engine (confident we can do it within the hour by this point) and he said he'll let us know. That was last week.
Rang him today for an update, he now reckons it can be jigged with the engine in so it's being done first thing tomorrow morning! Excited!
Oh and ordered a driveshaft today for when its jigged, should be here Friday
