cervantes.es or other certification

Hi all

Has anyone done any courses with cervantes.es. I am looking to learn Spanish but would like to have some certification to put on my cv as i feel it would assist with getting a job if i needed it.

Has anyone done course with cervantes.es. specifically the online one? I would like to do the classroom one but im based in limerick and it appears it can only be done in Dublin.

If not cervantes.es can someone recommend some other courses i could look at that provide worthwhile certification at the end of it?

Thanks

D
