APP for navigation - "Replacement Navigator"

This software/app is for navigation in car and guidance for a newspaper and paperadd-route where multiple persons drive the same route. There are around 70 to 300 drops on this route and around 30% of the drops have special information for example: "Put in mailbox at house" or "put in tube behind the trashcan". I have new people driving the same route each day and there are a lot of training and learning involved in knowing all the details and driving to the correct addresses. The point of this app/software is to make everything very easy so a new person just can open the door to the car, and be guided to where he/she should drive and also know what to deliver. In the attachment you can see how it works now: (a video = [login to view URL]) Its very "analog" meaning everything is done by memory/experince and all information on what to deliver is on paper. I want all this information to be served in an app/software so everyone could sit in the car and drive the entire thing without any prior information or guidance. Required: Guidance: door-to-door navigation based on GPS-points delivered each day in a spreadsheet. Here information about what has to be delivered and to which address. This list changes from day to day. Required: Each address can have special information as for example: - A picture showing where to drive or where to deliver - A Video showing details on where to drive / what to deliver. - A description telling where to deliver - Programmed so its easy for other programmers to change/modify/add changes or additions. Platform: Android as a minimum. Could also be windows-based or Apple/Mac if the argument for this is good. Attached is 2 files: 1: Video of how the driving works now. 2: 2.1: A spreadsheet containing information about all the possbile addresses and GPS-coordinates ("All addresses with GPS and [login to view URL]"). 2.2: A spreadsheet containing information the actual "day-list". Here information about what has to be delivered ("Delivery-example-updated each [login to view URL]"). 2.3: Image-examples(2 pcs) - (Filenames are mentioned in the "All addresses with GPS and [login to view URL]" file) 2.4: A video of driving-instructions in video-format. (Filename is mentioned in the "All addresses with GPS and [login to view URL]" file) I will consider all bids if: - Your bids clearly reflects that you have read and understood all information. - Have good feedback. - Have experince in apps and navigation (please let me know about this) - Best if you contact me in PM and tell me how you intend to solve it / what platform to use. Payment: 100% payment done via Milestone. 100% release of payment when app/software has been handed over and is has been tested for a minimum of 3 weeks. After this has been finished I will need additional work done on the app like features and additions. Bid what you estimate it will cost I just set USD 500 to 1000. Ask if in doubt prior to bidding if anything. I will choose the lowest bid with best feedback.
