We specialize in book creation -- from concept to cash register, and we work primarily with highly motivated authors who intend to self-publish their work rather than to rely on an outmoded traditional publishing model or to turn their book over to a "packager" or "vanity press." As OPA Author Services, we provide direct services from concept to the printing press, then we refer clients to an independent, highly credentialed and validated consortium of experts in all phases of book promotion, publicity and marketing to bring their work to public view and sales success.
