Re-Code/ Rebuild a GPS based app

***Please STOP*** If you don't have experience with phone based GPS (not transponders) and are not a 'TEAM' please do not apply. Now I ran this by a lot of people and they are all telling me the same thing. The coding is a mess and it needs to be totally re-done. This app started off with 2 versions, 1 for the user and the 2nd for the client/friend and when I had them combined is when all the trouble began. Now I am in need of a mobile 'company' to finish a project that was designed by someone else but is just not stable. This team (It's amazing how many people claim to have done this, and how many times I have ran this ad) would be a company that is especially good experience with 'GPS'. Also with Codeigniter, Linyx, port configurations etc. And of course iOS/Android mobile and both tablet and iPad app development. This app has 4 main features and works cross platform on phones. It works almost like 'Life360' or 'Uber' where you can see the driver coming to you, or track the person/client etc and also has a panic button which sends an sms of your exact location, and calls the police. It works also on tablets/iPads for the 'Open House Point Feature' but does not track these devices which seems to be one of the hurdles), makes appointments with prospective clients and more. Please read the attachment and also watch the videos at [login to view URL] for how it is supposed to work. There are ‘Users’, ‘Friends’ and ‘Clients’ that use the app: [login to view URL] [login to view URL] Please submit your estimate along with ETA for delivery for the work described in the attachment. The app is live and we were trying to debug it, but that just does not seem to be working. The source codes will be available when an agreement has been made to proceed and an NDA will also be required to view them. Please also send samples of previous GPS work performed, which will be verified. And please don't send me somebody else's work trying to claim you did it if you did not. Hoping that is a good description and I look forward to your bid. Also please provide an estimated time frame to complete. Thanks!
