woo you did some old school job  - its really pain that stage, but after 
the initial work the fun starts ;D


Now:
For that you need to georeference the rasters. having sheets (or 
rasters) of data I've found the 'MapSheetAutoGenRef' plugin (3rd party 
plugin) that supposedly auto georefs the rasters based on SHP files you 
create along known grids.
