Hi,
I am a software engineer with 4 years of experience in web technologies, especially JavaScript/jQuery/Backbone. I haven't seen a project quite like yours here on Freelancer and this bid is out of sheer curiosity: what could those scripts be? :) Anyway, I would like to take a look at the scripts even if you don't plan on hiring me, just so as to gain some perspective on the amount of work included in this kind of projects within this kind of price range.
Kind Regards,
Vladan
