Translating the website / adding a slider

Hi guess,

I´m trying to translate my website for the last couple of days, but I´m getting from one problem to another. I´m using the Sydney. Do you have a plug-in that you would recommend for translating the website into Spanish, German and Portuguese? I already tried “qTranslate-X”, but this is very buggy and doesn´t work well with the editor. Do you have a plug-in which you can recommend?

At the moment I tried to just set the paths by myself and copy all the pages and change the language in those pages, as you can see in the link: http://www.itxp-global.com/de

I just copied my home page and changed the services, but obviously, the slider doesn´t show up. Is there a way that the slider can be shown on this site, too?

Thank you very much in advance!
