Help ... Help me complete my first book

My novel is half laid out for hardcover UK printing by Amazon, with an incomplete cover design. These were done by family members whose work obligations prevent them finishing the job. I need someone to bring it over the line. Hardback, Ebook, Kindle and Paperback versions to Amazon UK specs. Its my first novel, my baby - i need someone who can work fast and thoroughly, dealing with an author who has no clue about design or the programmes onvolved but is PASSIONATE about getting it right!
