Modify existing project, Add dynamic routing with a minimal budget

I encourage new freelancer to bid on this project and make this as an opening project in your freelancer career. I reposted my project because there's a lot of freelancer who bid so high that i can't even afford them. I will only hire people who can work below their minimum requirement because i'm still a student, I don't have high budget. Project : I have a current mobile app, I want you to add a function that will automatically build another path when the user lose it tracks in the polylines/path that the app created. For example The user wants to go from A to B. The application itself will build a path from A to b. but then the user choose the wrong side of the path making him out of track in the path that has been build. I want you to add a function that will automatically and dynamically adjust the polyline/path when the user choose another road/side. I will hire people who read project description. Test the app: [login to view URL] Open your internet Enable your gps/location. onMapLongClick to add markers. Click begin routing to create a polyline. As you can see, there's a blue polyline going from your location to the added marker. If the user goes out in the polyline or become out of track. The app SHOULD recreate a polyline or add another path going the added marker you created. or you can add Another polyline going to the ORIGINAL polyline so that the user will comeback to it's original path. I will give you the source code. BID REALISTICALLY. IF YOU BID lower than 2000php, There's a higher chance that i will hire you. I am serious that's why i need serious programmer. BID 2000 so that we can talk about it. For all those people say my bid is too low. Read Again.
