I have a requirement to build an application on iPhone that allows doctors to select from several short questions on 10 pages, and then uses the selections to make a simple diagnosis for a particular case.
The data is not saved or associated with any individual - it's just a quick way of running a diagnosis based on a medical textbook.
I have all of the questions and the logic already but I don't have designs or mockups yet.
I'd be interested to know how long this should take and whether the budget is reasonable.
