We need to implement a demo for a client on anIphone but it doesn’t need to be real. It is just for them to get the feel of the application. I have prepared images representing everyone of the application screens, so your work would be to generate the application and make it possible for the user to navigate through the application but without doing anything else. In .NET or Java I would be able to do it in a few hours, so I expect that it won’t take you longer than one day to do it. We need it for Tuesday at the most. That’s the only important deal and that's why we pay it so well.? But we need to be sure that the work gets done correctly and on time.? I’m sure it is a reasonable to ask for this.
The most important here is the deadline. If you are not sure that you can get it done for? tuesday, simply forget about this project.
