Architects plans redrawn in Illustrator (CS4) to 1:50 @A1

I have reversioned a set of plans for my house which I downloaded as rasterised PDFs in Photoshop. They have been rejected by the planners as they are at the wrong scale. Ideally I need them redrawn in layered Illustrator CS4 vectors so that I can tweak any design details going forward. There are a couple of inaccuracies in the originals that I would also like correct - the detail of the roof tiles and detail of the timber frame to South gable end and can supply photos to work from. I need this done this weekend if possible. Thanks!
