Thanks everyone foe your comments and suggestions. Whilst we have all been musing about who is best, and why on earth a new boater would not want to move a boat themselves my husband has found a husband and wife team who will move our boat for £120 a day, and have agreed to do long days so that we can meet them at the marina on a Sunday (got to keep to weekends because of work).
I'm not sure what you all think , but I'm very happy with this and looking forward to settling into boating life when we retire later this year.
