Hey! My name is Martin and I am ready to work!!
I am actually doing this (uploading an ebook to Amazon) for myself for a book that I have been working on. It's apart of a presell campaign, for this particular book I want to see how many official "sales" I am able to generate before that actual books release date. Presaling ebooks on Amazon isnt something most are familiar with. It's one of Amazon's best kept secrets. It is tedious however, but in that same breath an excellent way to measure the strength of a marketing strategy.
If you are thinking of writing another book soon, you might consider offering as a presale before you finish. It's a sure fire way to validate a fresh book concept.
Speaking of Marketing, have you considered a marketing strategy for your ebook? It's important to consider where you can get "new" readers to experience your creation. One great way to start might be guest posting on a blog in a similar niche as yours. Another soild way to get more readers is, starting a news letter and emailing it to your contacts. Sharing the link to your social media pages wouldn't hurt either.
That being said, send me a copy of your book and I will have it coverted to the proper format and see to that it is uploaded to Amazon's marketplace. Start to finish it shouldn't take more than a day.
