I am looking for a Ghostwriter

I'm planning a couple of projects and books for self-publishing. I have a couple of concepts ready and genre's that I'm looking at. Even though I'm a creative content creator, I'm not a skilled fiction/how to/journal/non-fiction/biography/children topics-writer and require the services of a professional ghostwriter. This is for e-Books only at the moment. Depending on the launch and demand, will I look at paperback and audiobooks. Ideally looking for someone that are a specialist in their field/genre. I'm starting small, planning to go big.
