Hello,
Actually, I am Actionscript 3.0 programmer (AS3) for Flash, Flex and Air. And as you know these days migration from Flash to Html5 is happening. Thus, I am bidding on this project accordingly. I have used Greensock in almost all of my projects in AS3. So, I am quiet familiar with GSAP for AS3 and also for javascript. My rate is little bit higher than your range, but I will make sure you have chosen the right candidate with right price.
Thanks
