SVG File..., Controlling output size and back-saving? Options

[Brock]

So I have a few A4 documents set up and the client wants them in SVG format – at 70kb each (5kb leeway either way), and he needs it to be backwards compatible with CS2 (I'm on CS5).

The only time I've ever exported to SVG was simple – export PDF from Indesign, whack into Illustrator, Save As SVG etc.

I do that with this job – file is 200% larger than he wants. On top of that, there seem to be no options to back-save it to be compatible with CS2 (you can back-save when saving an AI file but not SVG it seems?)

Is there some way I can do what he is asking? :/

(I work in print, SVG is used for web AFAIK so I don't really know a whole lot about it.)
