Our proposals are clear and detailed.
All factors that come into play when calculating price are clearly indicated: number of words, unit price, project coordination, deadline, level of repetition compared with earlier versions of the document…

Our cost-estimates are firm.
with no hidden surprise. Unless the text or deadline given in the proposal is changed, invoice and cost-estimate amounts will be exactly the same.
We commit to informing immediately of any change that may have an impact on your budget.

Check for yourself : ask for a cost estimate, no commitment.
