Most folks on this site do carry their own things and make their own arrangements as they go along, but there are quite a number of tour companies who book individuals and groups, arrange all accommodation and transport your luggage. Just google "arrange accommodation transport luggage tour companies camino de santiago" and you'll find a number of them.
just a note that if you have your luggage transported you may limit your accomodation options. I haven't seen this myself but understand that at the public albergues pilgrims who carry their packs may or will get preference to those who have their luggage transported. I don't what kind of accomodations you were planning on looking for and I quie enjoyed some of the private alberges I stayed at which I didn't find too expensive.
That being said I hope that you enjoy your Camino. There is no right way of doing it and sometimes circummstances dictate.
