Convert an Indesign brochure from 8.5 X11 to a 5.5 X 8.5

We have a brochure that was made in Adobe Indesign . It was made for a 8.5 X 11 layout. However, we want to print it as a 5.5 X 8.5. So we need the pages adjusted so that it will fit that layout. Everything has to be arranged so that it will look exactly how the original one looks, for example there cant be extra "white space", etc... By accepting this project, you agree to fix it up until we are satisfied.
