Please message me if you like and ask any questions you might have about walking the Camino Frances.
There are lots and lots of small tour companies, though many people prefer not to use them so they can arrange their day and sleeping arrangements more spontaneously. You have no freedom to do that when an agency plans your Camino.
Bag transfer is available everywhere and costs between 3-5 € per day. Very easy to do on your own.
Once you join one of the forums, especially the one from Ivar which the previous poster linked to, you will find lots of answers to your questions. If you are in the US, consider joining one of the American Pilgrim groups. There are lots of FB pages too. Pages for women only, pages for slow strollers, pages for the various routes, pages for Ivars' forum, pages for Vegans and Vegetarians, pages for American Pilgrims, Canadian Pilgrims, etc.
