I have an application that is complete except for for the offline map.
My map component is only for the Paris area. I have all of the tiles already downloaded.
Again, all you have to do is install a working map engine on the app. I will send you the source code of my app for you to install the map on it.
ONLY developers who have developed offline maps before need apply. $400 is the maximum for this project. If your hours will go beyond this budget than don't bother applying. I'm only interested in developers who have done this before and can get this relatively simple job done quickly.
