Hello.
I am a GIS expert and Web&Mobile developer.
Since 10 years before I have been developing GIS applications.
I graduated GIS special education course and I have rich experiences for development Desktop,Web and Mobile GIS applications.
as a GIS developer, I can develop any kind of GIS application based on ArcServer,GeoServer and GoogleMaps,OSM,MapBox,PostGIS and PostgreSQL and MS SQL.
And I have many Web technologies such as PHP, Java,C# etc.
I checked your requirement and I think that this project would be realized by ArcGIS server.
I would like to heard from you.
thank you.
