Validation of Swahili-English translation

This job will entail:
1) Listening to a number of Swahili focus-group discussion and interview recordings
2) At the same time, looking at the drafts of the English translations of these interviews
3) Filling in any missed conversation or details in the English translations/transcripts

Basically, we need to be sure that the written transcripts in English are capturing all important details - not a re-translation. All audio and draft transcripts will be provided. The consultant should be fluent in both English and Kiswahili (specifically that found in Tanzania).

Please send quotes that propose a price per hour of listening/checking. (X $ for each 1 hour of listening, for example.) Thanks!
