Enfold spanish translation

Hi!

First I want to congratulate Kriesi for this template, I have not seen much yet but it looks so pretty.

I want to translate to spanish language all the english strings wich are contained into the theme, but I prefer not to buy the WPML plugin because it´s very expensive for me, and the main problem that I have is that I don´t know a lot about PHP and it´s so difficult for me to find PHP pages which contains strings.

Could you help me to solve this issue with some kind of advice?

Thanks
