Whatever you do really consider transferring and/or assigning your copyrights to anyone outright. Today your manuscript may not be worth much, but one never knows what will happen at sometime in the future. Below is one of the options of the website. I'd stay away from this option unless the payout was gigantic and/or you really, really needed the money. Under this plan, you as the author, and we as the publisher, agree on price and terms of buying your manuscript. You receive a onetime fee, with no future royalty payments. We make all decisions as to style, paper, printing, binding, illustrations, time and manner of production, price, publication, and all other decisions relating to publishing, sales, and marketing of your book. Copyright and all subsidiary rights belong exclusively to Publication Consultants.
4-We Buy Your Manuscript Outright
This plan seems to be best for authors who want to sell their manuscript for a anytime fee, and don't want further involvement in their book.
POD is print on demand. Meaning you print when you need more books. If you are your own publisher you'll be printing on demand. This also means you'll be responsible for editing, graphic design, marketing, promotions, distribution, royalty collection and so forth. The process is worth the experience and since you'll be doing most of the work anyway you may want to consider starting your own publishing company to publish your own books.
