I’ll give you a star for this. I suspect I haven’t been clear enough 
@nvrau I don’t know of any tool that will allow you to do exactly what you want. If you’re using a CMS such as WordPress, you may find events plugins that may get you closer but your case is very particular and, if this is a one time only thing, I wouldn’t even install one of those.
You’d be better off with a custom script. If you can’t do it yourself, you may find someone that will do it for you.
Try flippa.com or oDesk or elancer. It shouldn’t be expensive. Do be clear in your description and explanation to get a realistic quote.
