Replace YouTube Embedded Video with local Embedded Video - Joomla 2.5

Firstly, if you are not experienced with Joomla please do not bid. We have someone very capable already that could take a look at this, however we have promised the client that only an experienced Joomla developer would now look at the site. We require a Web Developer to replace a YouTube video on a clients Joomla homepage with a file locally. So, no streaming from YouTube. The client site is Joomla 2.5. We will need someone to remove the embedded video and use a module/plugin to then host the video (.mp4 152MB) file. You will receive FTP and Joomla admin credentials. All work will be logged. We require any files/data that you have downloaded as part of this task to be deleted. Just to note, we have already had one dev fail to make this work. The file was tested and is OK, however when played on the site only audio was heard, no picture. These changes have been reverted.
