Russian Voice Overs for English Video Clips

Hello I need Russian voice overs for a videos which are in English language. (No written script available) There are 5 video clips and approximately 35 minutes in total. Out of these 5 clips, there are 2 clips where you also have to change a phrase which has been used several times (around 6-7) with a different phrase. There will be such 3 phrase replacements which means there will be 6 russian voice over clips out of these 2 clips. This means you must have the experience in audio and video editing and production to minimize your work. No such phrase replacements need to be done for the other 3 videos. Therefore, there will be 9 clips at the end of this project. Your Russain voice over must sync properly with the video and the voice should be clear without any noise. Existing video's duration is around 30 mins. You have to edit one phrase of the video which has been repeated 3 times in the video with three different phrases. Therefore, you have to deliver 3 voice overs in total with that simple change. This means you should have the experience in audio editing as well. Native Russian speakers who have a good voice and experience in audio/video recording, audio/video editing and production are welcome to apply to the job.
