Hello,
I am highly experienced mobile developer (12+ years of experience in mobile games/applications development).
As I am currently building my portfolio in Freelancer service, I would be happy to create the application for you for as little as 5$ (+ 5$ which is taken by Freelancer service). What matters for me is the positive feedback from you, not the money.
Actually, I already did the application you need :), so if only you could provide me the details about the POC you need, I will finalize/re-skin and clean the project and then send you the source codes and/or application itself.
Best Regards,
Tomek Wagner
