subtitulos en ingles a video (con voces en español)

I am looking for someone to add English subtitles to my Spanish-language video. The subtitles need to be synced with the video's audio, which has a length of 1 hour and 6 minutes. The text has 20,000 words.

Ideal skills and experience:
- Fluent in both Spanish and English
- Experience with subtitling and syncing subtitles with video
- Familiarity with subtitle formats (SRT, VTT, Sub/IDX)
