I bought the ISO 14000 Standard Document (Environmental Management) for $170 earlier this year, so it is not expensive for a company. Not sure how the "technical documents" ala ISO 9660 differs in price.
The certification on the other hand is a bit more costly though. My estimation of the certification cost for a ~20 people company if you do it as frugally as possible ended up at $18000 for the first year investment, and $6200 recurring the following years.
