I can record your script in Russian with a tight deadline providing professional quality at the same time. I can sync the voiceover to the existing video or read it wild. If you want to listen in to the process to make changes. Here is the list of the equipment I use (microphones - Rode NT1-A and Shure SM58, sound card - Focusrite Scarlett Solo, computer - MacBook Air, DAW - Adobe Audition and iZotope RX 9). Let me know what you have in mind and I will find a way to make it happen. I'm open to record a short custom demo so you can get a feeling what the audio will sound like.
