If that's what you have to create, then that's what you have to create. If you don't want to do it yourself, try http://www.rentacoder.com/ or some such service. Or if you prefer to have someone who hangs out at JavaRanch to work on it, I suggest to contact them directly to obtain a price quote.
If, on the other hand, you were hoping to get help for free, then be aware that JavaRanch is NotACodeMill. Instead, it is a place where you can get help to solve your Java problems. Many people here will be happy to do that.
So: What ideas and/or code do you have so far, and where are you stuck making progress?
