PURL Technology Setup

I'm looking to set up a PURL campaign (personalised URLs).

Initially I just want to do it for one campaign but if it works I would like to be able to use the technology for other campaigns.

So, what do I want it to do?

- Be able to either personalise the sub domain or the end of a domain: johndoe.domainname.com or domainname.com/johndoe
- Be able to personalise parts of a one page website. I need the technology right now. I can build the website template but I'd like parts of it to be personalised like a field to enter the person's name and company name.

I need this for an initial campaign of about 500 recipients but would like it to be scalable. I guess there would need to be some kind of table at the back end, maybe that you can load a spreadsheet with data into.

If you've built something like this before then great - show me examples. If you haven't that's fine, just let me know how you would do it.

I really don't know how long something this would take to build do not sure about budget.

Any questions, please do not hesitate to ask and I will respond to every question I get.
