239212 Create PHP Link

I have a domain name auction where the billing feature was never fixed by the original script builder at rad nics.com. I need someone to turn my "buy now" text into a link to a form that I create. I will give you the name of the ] page to link to, I just need someone to create the link becuase I dont know php. the site is at domainoid .com and you can see the "buy now" text under "high bid"\ Please email me with any questions.
