clone and upload a website to my host

I want a clone of a certian website that I do not own. Products and all. I will change meta tags and page title myself to make it seo friendly after it is built. it is a ecommerance website. and I would need it to function as one after complete. I am familiar with running a oscommerance [login to view URL] it could be adopted to the cre loaded oscommerance shopping cart it would be great It has to be uploaded to my host after cloned. my max budjet is 300.00 usd paid by money bookers.
