Javascript expert / Mobile app developer using Application Craft

We are looking for a developer to assit with creating a mobile app using the .applicationcraft.com cloud system. This system uses HTML and Javascript.

We require map locations to be populated from a mysql db on a google map (using a the gmap api / widget).

We only want to show locations depending on some date/time logic and also want to colour the markers according to some date/time logic.

There are other features that we will want developed over time.

I am looking for a long-term partner on this with proven results and affordable cost.

Thanks
