Build script / webpage

Hi there. I would like to get a very similar script like3 [login to view URL] like a clone I mean all pages and forms that you will find on the link above. I need also to put some ads banner and stuff like that. I have several domain names for sale and I would like to have my own parking script. Can be: script working with DB. an admin page where I could add my domain from there or HTML templete where I have to add content for each new domain. I guest that the option 2 will be cheaper but I want to get your bid and opinion. thx
