Do some 3D Modelling

We are creating a book and we need the front cover to have some 3D look to it with the colors that we are providing. There are 38 different illustrations/pictures that will be inside of the book. I need each illustration/picture, that I have attached in the pdf, to have a professional, 3 dimensional look to it. The type of feeling that i would like to express with the pictures throughout the book would be like a SPIRITUAL-COSMIC type of feeling. I will attach some other pictures as well that are examples of they type of look that we are trying to get to. Delivery: We need each of the 38 pictures/illustrations to be in 3 different formats: 1.) PDF (300dpi) 2.) JPEG (300dpi) 3.) Original Program File Format and ALL of the source files (psd/3ds/or whatever original program format that is used) (IMPORTANT THAT THE ORIGINAL FILES ARE NOT FLATTENED. WE NEED THE LAYERS IN THE ORIGINAL SOURCE FILES SO THAT WE CAN MAKE CHANGES IN THE FUTURE AS NEEDED.) *** ALSO, need written release of any copyrights warranted on all works PAYMENT METHOD: Designer will receive a milestone when the work is complete I will RELEASE the milestone after the work is delivered as stated above. This is how we handle all of our freelancer projects that we do. Please do not ask for a milestone payment before work is performed. Please see my review if you need to. TIME FRAME: We need this project completed within 5 days. However, sooner is better.
