Hi.
May I call you John?
I'm fully available roughly around 10-20 hours a day to work on your project for the next 3 days. I also have some experience in either building mobile-responsive sites from scratch, or based from existing desktop version. Could I see first about the latter (a link to your existing website)?
My main skill is in HTML5, CSS, native javascript and jQuery so I think I might help. Am familiar too with XML or JSON, since I've used them a lot either for frontend or backend works. I know Bootstrap framework, and a few others which can help building mobile sites fast, but I don't use them. They all tend to make a site unnecessarily "heavy".
It'd be great if you already have a couple of general design or rough scratches of your site in mobile-devices. So, may I take a look? Please share them with me.
Warm regards,
Hendra D.
