Help with Dropbox or other photo sharing apps

I am beginning to take the next steps in photography and actually taking clients. I am having trouble with sharing and uploading my photos the fastest. Everything Seems so slow drug out and inefficient. I want to give my clients access to their photos to chose which ones I edit and then reshape those edited photos with them. I’m not sure what plan I need or how to navigate this any advice? via /r/photography https://ift.tt/3g7AJ2k
