Format & Design Mystery/Thriller Novel for KDP

I'm seeking a professional to format my 31,000-word fiction novel for Amazon and KDP. The book is a Mystery/Thriller, so the cover will need to reflect this genre. In addition to the cover design, full interior formatting is necessary. The book's final size will be 5 x 8 inches.

Please, if you have experience with book formatting and cover design, particularly in the Mystery/Thriller genre, I'd love to hear from you.
