Reposting duplicate a website

I want to use the following website [login to view URL] as a template for a new website offering the same product only to a completely different audience. I like the function of this website, only I'd like to use paypal as the payment gateway. I don't need the content or the css created as I can do that myself - I just need to the coding done to make this function like this one does with the tools to create emails or upload emails, account management features, etc. Our budget : $150 max. Just to clarify - what CMS platform would you propose? Joomla which is PHP or something in ASP.net as stated below? I ask, because I already have a PHP host that I use for multiple website but they do not support IIS for ASP. I will award the project within few hours. Good communication is a must. If you won't reply for next 24 hours after posting your bid, please don't bid.
