Code a unlimited link generator

I need someone to code a unlimited link generator that I can use on my website. When someone clicks the generated link, it it has to take them to a page where it asks them to put in their name. Once they put in their name it takes them to another page that gives them a number. This certain link must keep track of what number it gives to people. So the first person to click the link gets #1, then #2 and #3 and so on.
