Israeli or Hebrew speaking PHP/Javascript Developer Needed Hourly

I have a WordPress site that teaches beginners how to read and speak Hebrew. Everything is driven by MySQL database, and we use WordPress shortcodes that put Hebrew words on the screen. When a user clicks the words, the appropriate .ogg or .mp3 sound file is played using SoundManager2; all software is HTML5/Javascript-based and currently works on multiple platforms (Web, iPhone, Android, tablets, etc...) via multiple browsers, and must continue to do so. I need someone who can create additional WordPress shortcodes to do functions such as: 1) Auto-Read a longer text, one word at a time (at various speeds, by playing a serious of mp3 files, and highlighting each word as it is being played). 2) Create several sound file players for playing various blessings, chants, and Hebrew songs. 3) Add AJAX logging of each user click to history database table 4) Quizes or Drills, such as take existing groups of words, display them randomly on screen, play sound file associated with each word, and let user click the word that was played, store results in user history table. 5) Misc work as required Need someone willing to work about 4 to 10 hours/week as needed. My time is limited to test the results and to give feedback. Digital agreement to NDA (Non-Disclosure Agreement required).
