I've tried to sell them the app before actually starting to build it without success. I've tried to sell it for month now, but as it is a HUGE company with only old school and out dated tech... i haven't got much luck.

The reason why i'm asking for it legality is because i'm planning to launch a marketing campaign to attract more users (actually have 2769k on iPhone/Android without any marketing): i'm trying to provoke them with the campaign to make them buy the app and rebrand it.

Thanks for the feedback.
