Hello!
I am interested on this project, we have a lot experience on it and already we have experience developing applications. But, can you give me more details about this one please?
Do you need a database or you already have one, you will need a registration page? obtain data using json, interaction with APIs?
Contact to me for details, I can provide you full access to our code while implementing, using SVN or GIT repository and I hope we get wit this project.
Also, if you want to contact me via Skype this is my account: cristiansanemeterio
Regards
