Just to say that the tariffs for certified translation are fixed and no legally authorized translator can undercut the price.  While the cost may seem high, you have to accept the legal implications of the work and skill involved.  Indeed, many very competent and experienced translator do not have this additional qualification.

As to finding a certified translator, the Faculty of Interpreters and Translators will be able to provide names as also the Geneva

association of professional translators which you can find via google.

I can vouch for them:
