Install Translation Plugin and Copy German Text to Wordpress Website

Hi, I need someone to install a translation plugin on a Wordpress site and copy translated German text onto the pages on the website. There is 2200 words to copy. It's small static site with around 10 pages. I will provide the word document with the translated text for the menu, page content etc. Freelancer just needs to install a plugin and copy the translated text to the correct parts of the site. Need suggestion on the best free plugin to use, needs to have a flag or widget so the user can switch the site easily between the two languages. Budget for the project is $35 and need it done as soon as possible. Immediate start. Thanks
