Updating JWPlayer 6 version (To HTML5/Youtube) on a Joomla 2.5 website - Repost

* I'm reposting since the last programmer couldn't complete the task - please do not bid if you're not capable of completing this task. ---- My website is running JWPlayer 4 in Standalone as part of custom-made competent (also as an audio player). I would like to update the Jwplayer to version 6, already purchased an updated Joomlarulez/jwplayer plugin, since the current version is outdated and not supported by many browsers. Please note that the component: - Allows me to insert a youtube link that is displayed on my product page - Allows me to upload mp3 files to the product page (custom made design player) - Payment is made ONLY after the task is fully complete. - The task will be implemented on a copy of the website (provided by me) and would be applied to the live version after the desired result is accomplished. - It's a simple task, looking for a fast and straightforward solution/service. - Must work perfectly on all​ browsers (including Mac OS)
