Hello Adsgencia,
I understood the requirement and is achievable. I can leverage my experience and skill set in building the app. Do have a look at my portfolio for the Apps i have delivered to some of my clients on IOS.
I usually take the agile way to completion . It gives you the flexibility to amend the requirements of your app midway ,should the requirements change.
Do let me know if we can connect on Skype for a short discussion on the project.
Regards,
Ashwin.
