There are a number of travel agencies who specialise in providing services.
The simplest are ones carry backpacks/luggage from where you have spent the night to your next night’s accomodation.
Others will book accomodation for you for whole or part of the Camino and offer luggage transfer services as well.
Still others provided guides and you can join a group where everything is catered for.
