Build me an appointment system.... please see project description for more details

Update1: Please read the project description clearly and - Freelancers with NDA signed only will be considered, others will be ignored. Update: This is an update to the project. We have upgraded the project to be NDA and IP Agreement as well. Whoever is still interested, please go ahead and sign those documents so that we will be able to share the detailed requirements and take the next steps accordingly. ================================================================================== First of all, this is not a complete list, but a high level idea only. 1. Appointments system which does features similar to: a. Add an appointment between two parties on a particular event b. Several ways to set and get reminders for the appointments c. Should work seamlessly over phone or PC or any other device. 2. Should use modern tools, practices, platform and methodologies. 3. Code should be written clean, indented, commented properly (and no plagiarism as well, unless that code has a public license including to be to change and use, and without any restrictions) 4. Full code should be given. 5. We can work out an NDA or equivalent to be signed which indicates the code or related things are not shared for your future projects purposes. 6. Should be comfortable to work in an agile fashion and dedicated to this till it finishes. We will discuss with the right freelancer/team to get this done. So I understand you read the entire description mention the word "future is here" somewhere in your bid (not at the beginning) - (For people already submitted their bid, please update it accordingly) Timeline is no more than 25 days (this should include requirements gathering, development, testing, release, and ongoing support) Budget is not too much for this project, but with the right freelancer/team we would like to have ongoing relationships and potentially there will be future work too.
