You can use a couple of different strategies to promote your book, depending on whether you've placed it on multiple platforms or are using KDP Select. If you've gone the first route, and have print copies available, it may be worth it to pay for a Kirkus review. Kirkus is expensive, but it is the fastest way to reach a lot of crucial markets at once.
If you have decided to publish with Amazon's KDP Select, and want a good way to reach as many people as possible on your free days, there are several paid options open to you. Almost all of these are more effective than free services, though some are more pricey than others. (For a single book - not part of a series - you should stick to the cheaper options.)
No matter how you advertise, you will have to plan ahead of time to make sure reviewers are lined up before you begin a promotional campaign. It is always a good idea to coordinate your efforts, for example arranging talks at local libraries and bookstores, sending press releases announcing your upcoming release, and hitting every social media outlet and online reviewer so that your release makes a splash.
I've only listed below the services that authors have reported are the most effective for promoting their books. There are many, many more. For a full listing of paid sites see:

A word of caution: Be selective and research before you spend you money. Not every paid service is worth your hard-earned cash. If you are strapped, avoid paying for reviews altogether. There are plenty of reviewers who do not charge. Click on the link below for a list of nearly 300 reviewers who accept self-published books:

Kirkus Indie
Cost: $425
Bottom Line: You can get a lot of bang for your buck with a positive review. But a negative review from Kirkus is the kiss of death, so unless the review is glowing keep it private.
What they offer: Kirkus is the most prestigious book review service in the industry, and one of the oldest. All books are read by professional reviewers, who give an unbiased review of 250–350 words. Reviews for Kirkus Indie can be kept private or published. Because their reviews are distributed to Google, Barnes & Noble, Baker & Taylor, and Ingram, they reach librarians and major media reviewers (e.g. New York Times). Your review may also be selected to be featured in the Kirkus email newsletter, which is distributed to more than 50,000 industry professionals and consumers. The Kirkus website gets more than 1.5 million page views monthly
How to submit: You can request a review by clicking the Get Started link on the author services page. Provide as much information as possible about your book, choose whether you want to send Kirkus a printed (mailed) or digital (uploaded) submission, select either standard service (7-9 weeks) or express service (4-6 weeks) and pay for your review (standard service $425, express service $575).
