If you are in a great hurry, then I don't think it's worth wasting your time. We could always arrange it so that you keep working your designs, but give me concrete goals and a deadline. Should I succeed, great, if not, you have still your own work to rely on.
I'm still not clear on what your work flow would be. Would you be making a sort of "prototype" in tools that you know that I have to then translate to the actual GUI or would you be working inside the Mac Xcode environment making the GUI files themselves that I can then plug into my program and use?
In iPad design, however, I would be willing to learn the builder to the point where I can use the paper/photoshop concepts and hence produce satisfying design. I'm not sure about the learning curve in Xcode yet, so I can not really comment on that.
I'll just throw it out then: [email protected]
Let me know which communication method would you prefer, so I can reply to you with Skype or MSN Live initials.
I've been procrastinating for a couple of weeks now because I'm not happy with the visual design of the iPad app I'm working on. I'm no designer and would love to just pay someone to do this part, but if you're going to be learning this for the first time it will probably take you longer than it will me (even though your final product should look much better than mine).
EDIT: Wait, what do you mean by "I would be producing the design files"? Do you mean producing e.g. pictures of what the GUI should look like that I then have to go build myself?
