Hi there,
Your question doesn't make a whole lot of sense to me . Its subject is meaningless (everybody comes here for help), the forum inappropriate (how would this be related to Wrox announcements) and the question itself is very unclear (it's not providing any relevant information about a chosen technology, what you are looking for, what you've already investigated and built and so on).
Do you want to borrow or hire someone else's application for a while? Or are you developing this yourself? And do you need this in a couple of hours or only for a couple of hours?
In other words: can't make heads or tails from this request and thus cannot help you.
If it's really that urgent: spend 15 minutes reading this and then try again:
