I need a video editor to dub a video(VSL) in italian to french

I already have the cinematography of the video in italian and the translation of the video in french. I need someone to dub the video for me.

1st - Sincronize the italian video with the french audio (you can compare both texts to sincronize)
2nd - Modify certain parts of the video that I will specify for you and I have the videos the change already done
3rd - Do the captions of the video in french

Thanks
