Add Google Maps functionality to app (iTunes & Android) & website

The essence of the project is to supply the coding to allow the addition of custom Google maps and filtered search functionality, based on the users location or another chosen location, to our existing app (and in any others we choose in the future) as well as to provide the coding to incorporate the same functionality into a page of a Wordpress based website. The apps are to be distributed via iTunes & Play, and also as Web Apps. The existing apps are Phonegap/HTML/JQuery mobile based and the same code is used across both Android & iOS platforms. See attachment for more info. Thank you for taking an interest.
