I would like to know where I can advertise translation services?

Pace ads on automated advertising tool web sites, or subcontract with manual translation services already advertising there, ideally you would be able to only pay for ads for translations in your language.

You might in the worst case, have to setup your own translator broker system site that the translation page goes, your site finds paying manual translators appropriate for the current language, passing on the prospect.

I saw no Adsense ads on the Google Translate page,

This example has some kind of ad system

THe professional Translation link on http://www.sdl.com/aboutus/careers/careers.html I only found about 40+ on site translation openings.
