Dear Employer,
I've already developed a solution like Uber, named GoPlus, as you can see on my profile here at Freelancer and also at my website www.fabiobergmann.com.
I'm able to develop the complete solution, including web admin, web site, server, Android driver app, Android customer app, iPhone driver app and iPhone customer app, and modifications you need for $10.000.
I would be able to also support you for future changes for a tax per change you can discuss later.
Feel free to contact to talk more about it. Skyp fabiocberg.
Kind regards,
Bergmann
