According to
Preditors & Editors, Raider is a vanity press. If you want the best for your book, don't use a vanity press because you'll spend a lot of money, only to learn that they can't get your book into the bookstores.
Money flows toward the writer. Yes, I know, the Raider site says "Our extensive distribution system includes popular retailers such as Borders, Barnes & Noble and Amazon." That does
not mean that they will be able to get your books in actual physical bookstores (which is still where most people buy their books). It only means your book will be listed on the websites for Borders, B&N, and Amazon.
Searching for publishers on-line is not the best way to find publishers. The first sites that will come up are vanity publishers such as Rain and companies such as PublishAmerica (also not recommended). This is because they use the Internet to lure new authors to their sites -- and thus get money from those authors. (Real publishers lure
readers to their sites, not authors. Because their money comes from the readers. They actually
pay the authors.) The best way to find a publisher is to go to bookstores and figure out which companies are publishing the type of book you want to publish. Then use sites like AW to learn how to contact them, or get an agent. (And
don't pay reading fees, representation fees, etc. to the agent.)
You can learn a lot about publishing scams at Writer Beware:

You can also learn a lot by the
Bewares and Background Check board on AW.
There is a thread on Raider here:

It does not look promising at all. The company was founded by a former PublishAmerica author, which means their founder almost certainly knows as much as you do about publishing.
Also, their web design was terrible. Believe me, you can find a better publisher -- one that pays you.
Be sure to check that thread out. The publisher was founded by a former PA author
Note: Many vanity presses and similar scammers will try to contradict the information on Writer Beware, AW, and similar sites. Consider the source.
Who would you rather trust? A publisher that is nothing more than an overpriced printer? Or experts who have published books that you can find in stores?
