Author Website & Book Publishing and Marketing Expert

I have a five-book sci-fi book series completed and edited. I have digital cover art. I need a relatively simple, yet attractive website. I need KDP ebook formatting and publishing. I need research for, and initial contact with a reputable print (on demand) publisher. I need creative marketing services, i.e., someone who will actually do the marketing; not tell me how to do it. I need input and suggestions for all of the above.
