Pricing Guides or Estimating Guides ? Please help

We are looking for some printed or digital guides in Metric (not american sizes and paper weights) to help us with estimating. Franklin has them in the USA but they are no good to us we need European sizes and paper weights in grams.

These are simple pricing guides to help quickly figuring out paper prices, printing prices etc.... for different quantities i.e. 500,1000,5000,10,000 etc..... there will be sections for paper prices, printing prices, folding etc.... there are a few options in the USA but have found non with European specs ? Can somebody help ? Sometimes customers ask for too many specs, and too many quantity options etc... its really handy to have guides and go from there.

Thanks in advance.
