Amazon self publishing is no doubt a gold mine for everyone regardless of age or skill set.
Many Nigerians are making cool passive income just by uploading books of various niches and make money from it for life so far the books keeps selling.
The challenge of writing these books is what many people do not have time for. This challenge reduces their work rate and limits them from publishing more books.

The best solution for this is to get a ghost writer to do this for you. You can pay for bulk book writing. I mean, you send 50 topics or titles to the ghost writer and get them like 10 books per week. So the only thing you do is to design a cover using Canva and get keywords. Then you just upload. With this, your earnings will increase due to consistent books upload.
Where to get Ghost Writers are basically on freelancing platforms like Fiverr and Upwork. You pay in dollars, so you are paying more Naira. Still, this is much funds for starters.

When I started, i faced all these challenges.
This year I decided to set up a writing company basically for self publishers only.

Is this per word or the word count doesn't Mata for 1k per book. Please clarify.

We don't charge per words. We charge per book. Be it 76 pages, it's 1k. Be it 157 pages, still 1k. Same goes for words.
For example, a cookbook of 7 days meal plan will have lesser pages to 14 days meal plan. So also, a book of 20 recipes will have lesser page to a book of 40 recipes.
The number of pages your book will have solely depends on your title. We will get quality information to male it worthy, rather than working towards a target of 150 pages and fill it with nonsense.
Note: The least pages I've published myself is 65 pages and it has made me good money this month. It's the title, keywords that matters, then good content and not number of pages or words.
