iPhone application development question
I had an idea for a utility app when I bought my iphone 3gs years ago, and assumed something like it would be released soon as it seemed like a natural progression of the technology. I just recently checked, and was surprised that several apps have been released that utilize the technology for other purposes, but none do the task required. I personally know several thousand people who would pay about $10 for an app that will do exactly what is required.
So my question: How would I go about sourcing people to produce this app? I can front the money, but I'm concerned about the idea or tech being stolen along development, as well as producing it reasonably as I am not a millionaire.
Are there any copyrights in place for apps, or can anyone copy my idea once released?
Any ideas where to start?
