Children's book

I have compiled a children's book of a title page, and 16 A4 pages. Each page has roughly 5 lines of text, and 2 illustrations. The pages have been compiled already..in terms of text location, illustration location, page sequence, and illustration colour. I have attempted to do as much work, to allow for the graphic artist to do a quick and efficient job...and to avoid any guess work! I will provide; 1. The text files as a microsoft word file. 2. The illustrations scanned to suit....graphic artist to advise requirements. 3. A pdf of the compiled book...which needs to be followed. I require; 1. To choose a font style that will match the mood of the book, and be accessible on Mac and PC computers. 2. To scale the illustrations to suit the pages of the book. 3. To colour the images to match my coloured images. There is no need to choose colours...I have done this. Vector use maybe required, to allow for scaling of the coloured images? 4. To provide me with files suitable for Mac/PC e-book use, as well as for use in hardcopy publishing. I would imagine an interim review prior to finalisation. See the sample page attached.
