Customize a Website

I have website, which need some work below is requirement. Spend 5 minutes and answer exact if you can do? No Generic bids. I have a website which I made and now I have others who work with me who I would like to be able to use my website as well. Since my website lists products and people are able to order through a 3rd party website which is connected to mine, I would like my website to be duplicated into a replicating/affiliate website so the people who work for me can use this website but as if it is their own website. Further: My website is http://NaturalLivingPath.com. I am looking for the site to be exactly the same for all affiliates except when on a product page and a customer clicks "Purchase Now" this will take them to a page describing the transition to a third party website and how to order. Currently it is a picture of me and my information but I would like my affiliates to be able to have their picture and information. Then below this part, it says 3 different paths and when some clicks "Order Now" on this page, it will take them to the 3rd party website which currently has my member ID #. I would want this to be changed to my affiliates member ID #. Any question do let me know! Thanks.
