Looking for 20 freelance translators for European langauges

I am doing Translation Project Management.I have to conduct research on the internet to find out what professional translators are charging for translations for European languages. I should find information on 20 professional translators, either from information posted on translator directories/websites, or by contacting the translators if I don’t find the rates on any of the websites. I am doing research for a university project and I would appreciate your help. I should include the translator\'s name, email, rate for translation work and person\'s mother tongue.
