Applications for cities

I would like to make apps that compete with another company's city applications. The other company does an alright job with the applications, but the interface and the support behind the appilcations they make are poor, so I'd like to capture their unhappy customers and make them my own. Here are some of their apps: [login to view URL] [login to view URL] [login to view URL] Really, I'd like everything these apps already have and a little more. If you look at the apps you can see the features they would like: Business Directory using GPS that can be split into service types (shopping, restaurants, services, etc), Service Request (email sent to City about where something needs to be serviced), City Directory (directory of city departments and employees), Calendar of events, school directory (directory of local schools). The difference comes in how it’s all run. Currently, these apps have no interface to allow the cities to add or delete businesses, events or city employees. They require that the city send a request to the company and then the company will take weeks to get the request completed. I would like an interface built that allows the cities to manage their own data. Cities would be able to log in to a portal/CMS and update/add/delete/manage the following information: Events City directories School Directories The questions that the users sees on the Service Request page and where those Service Request's are sent Business Listings The cities should also have the option of performing updates via CSV uploads. To take it another step further, I maintain a MySQL database of businesses in the area. I would like the data in my database to be connected to the data in the App database (if possible they should be the same database). Each time a business listing is updated (by myself, by a city or by the business) it should be reflected on all apps and in my database. When a city manages a business they will have the option to Remove the business from that city directory, delete the business (pending my approval) or manage the information of the business. Additionally, I would like the control to create new apps easily. I would set it up in the database to hook to a new app and then I would only need to change a configuration file in the app code that would control the logo, color scheme, features for the business and area of the business. Then I would submit the new app to the App Stores under my name. The details will need to be discussed further, but looking at the apps should give you a good idea what needs to be done. I would like an estimate of how much this project will cost before I proceed any further. Please let me know if you have questions about this that are vital for you to be able to create an estimate.
