Publishing my book on multiple platforms.

I want someone to post by self-help book on multiple platforms.
I want at least 6 Platforms, Platforms optimization, Keywords ranking, Formatted copy in the KDP print file and EPUB file.
The Publishing Platforms are Barnes and Noble, IngramSpark, Amazon, Goodreads, Google Books, Apple Books.
Please send me what you have done in the past and the results of your work.
I do not want someone that does not have experience with this type of work.
I can do this myself, but as a time-saver, I'm looking for some help.
Thanks
