Ray, you need to be clearer; a CAMO and a maintenance organization are not the same thing and are separate. A CAMO oversees the airworthiness of the aircraft but does not take part in the actual spanner work. They instead ensure that all maintenance has been undertaken and that the paperwork is issued. The will oversee that all of the aircraft's scheduled maintenance and records are complete, correct and up to date. On being satisfied they will issue the Airworthiness Review Certificate. It should be possible for the current CAMO to transfer their records, if necessary, to the new CAMO on appointment.
If all maintenance is up to date then it is only the CAMO you require in the first instance. A large number of small maintenance organizations have formed a CAMO - operating in parallel - simply to undertake the 'reviews' of the aircraft they maintain. They might not be too keen to only take on the review paperwork unless they have also undertaken the actual maintenance. Try Multiflight at Leeds, I believe that they have a dedicated CAMO department.
