Dear Sir,
This is absolutely doable.
We have done many PhoneGap based mobile apps, using HTML5. JQuery,Node.js.
Generally, we work at USD12/hour and weekly paying basis. Here, i have placed a bid for 225 hours but, this can vary in real.
Reply back, so we can confirm you the estimation idea further.
Let's discuss this further.
Many thanks.
