make subtitle in srt format (English and German language) - 31 minutes

I have a video file which is 31 minutes long. About 20 minutes of that is in English and 10 minutes in German. I need the translation of the video in srt subtitle format. I already have the translation and transcription of the whole video in word document. All you need to do is create srt format subtitles of the video as translations and transcriptions are already done. Looking to hire a person who knows both English and German and have experience on subtitling works. Thanks!
