Hi,
I have gone through your post here and see that you need an app to update users of the various events , sites , and places in different areas of Florida Keys.
This app falls under the category of a Geo Location app and we have a high expertise in such apps.
Your project will require :
1) Web Server App to locate places and load some details like info,images about say retail stores , attractions , restaurants.
The server app will enable you to update the app contents at any time and the app will be updated immediately with the fresh content.
2) iPhone app to plot all POI ( Places Of Interests ) in a map and also list it under categories.
Overall we are very clear with the requirement and I am confident that our internal design + development team can deliver an awesome project for you.
I have shared links to our apps in your PMB and especially listed the GEO LOCATION apps separately for you to check our expertise in this domain.
We have developed the server , UI and mobile app for all our projects.
Cheers,
Rahul.
