It was very easy for me as I am an English native speaker, but also had knowledge of Spanish language so it didn't take much time at all! The process took about three weeks (maybe less) from when we first contacted them until they finished their work - which included translating every line into both languages plus proofreading everything twice before sending back out again just because there were some minor mistakes here or there after translation/proof reading once by mistake etc.. Also if you want your product localized within 3-4 months then go ahead otherwise its going be more like 5+ month timeframe since most products are still being released during this period anyway :) Great job guys!! You did such great translations too :).
