Hi sir,
I have read through your requirements, and I would like to discuss further more on this project.
I have been developing Mac and iOS application for more than 2 years and had apps submitted on both Mac App Store and App Store. Worked on Freelancer on many projects, I always dedicated with the app and flexible on customers's requests.
I would develop your apps in 5 days, the apps would be in warranty for 3 months, all minor changes would be completed as free. The first demo would be delivered at 3rd day after the project is accepted for feedbacks and changes. Firstly, I would have to look over your workflow and database configurations. Then, I would build a plugin or an application (which is more robust and powerful).
I really hope that we can be partners on this interesting project. And this be the first of many projects later if any chance.
Sincerely,
Dat Truong
