I would gladly do the job, should you choose my bid. I indicated 3 day because I don´t know the length of the video, nor how many versions/formats you need it in. If it is not too long and the amount of versions is not too extensive, it might take less time to be done.
However, if it is a long video and the compression versions are many, it could take a bigger span because the compressing process, once the settings of compression are configured, is a process done automatically by the computer that some times requiere rendering and/or exportation that lasts depending on the type of format and the length of the video.
Nevertheless, I am at your service.
