News Ticker Bar software

I am looking for a simple piece of software that is very similar to this news ticker ([login to view URL]) please take a look and download it to see how it works. the software I require will be very similar to this, however I would like it to have a couple more options - for example, being able to load a text (.txt) file into the ticker, the ticker positioning (top of screen/bottom of screen above taskbar), being able to add/remove words from the ticker by clicking on them, change text size, load program on startup, etc.... I will go into the few extra features I will require with the programmer. I would also like the same type of "10 day free trial" option built into the software, so that it can be used for free for the first 10 days, and if the person like it, they can purchase a registration licence (software key) from me. If you have any experience of building ticker tape software, please get in touch. This should be a fairly simple project for a decent coder. I am expecting a turnaround time of less than 1-week, including testing.
