An editable PDF is a good idea for design consistency. Only the fields that need to be changed should be editable.
As for saving your InDesign file for someone else to work on, under the File menu scroll down to Package.
Select Package and make sure to checked the following boxes Copy Fonts, Copy Linked Graphics, Update Graphic Links in Page, Include IDML (this is helpful if the person you're sending the file to does not have the same version of InDesign that you do), and Include PDF (High Quality Print).
It may be a good idea to send an editable PDF as well as the package InDesign file.
www.wetransfer.com is a good way of sending the file.
