How do I create a Microsite?

[ayrtonMG]

I am looking to create multiple microsites however, am not sure how to do so.The company website uses ExpressionEngine as the CMS provider and now we are looking to create multiple microsites that provide a unique page for each of the company's individual customers. Are there plugins I can use to create such a microsite?Are there microsite providers?I have already researched into this a lot, looking at WordPress, Adobe Muse, BrotherMailer and ExpressionEngine Extensions however, have not found what I am looking for. Would any of these be useful?Any suggestions would be great. Thanks! -Victoria
