Manual conversion costs

Righto for those of you who know, I've got a ba xr6t ute that I'm wanting to manual swap, now being from New Zealand there's not alot if at all places to get manual boxes for the xr6t so I've decided to look at possibly getting one shipped over from Australia and I was wondering if someone could tell me roughly (in ausd) what prices I could be looking at for a manual conversion as I haven't been able to find any actual prices
