Hi
I've a great interesting into your proposal as a iOS app expert.
I'm sorry to need more money.
But in your document, you want a little more functions.
There is no other way.
If u want to discuss in detail, please contact me.
In writing I-phone app, there are some risks such as supporting multi-version.
But I have enough experience with Objective C and Cocoa , can fulfill your requirement at top level.
Thank you for reading my proposal.
Regard.
