Wordpress blogs solution

Note: project involves adult content. If you are not comfortable viewing this type of material, this project may not be suitable for you. Hello, I need to install and manage multiple Wordpress blogs and I'm looking for an intelligent and economic solution. Since I'm not particularly familiar with the available options at hand, I define some basic points: a. I would prefer all the blogs to be managed from one central dashboard. b. The possibility of mass/bulk add new blogs, and mass/bulk modify existing blogs. I mean I want to perform actions like adding RSS feeds, or adding a banner to all blogs at the same time, for example. Also, modifying a new template for all blogs automatically, and so on. c. Be able to install mass install plugins. d. EASY to add more blogs with same settings with few clicks, in order to increase the blog network. I would like suggestions on the best option available and to go ahead with the implementation of the proposal. the network will have hundreds of blogs, upto 1000, at the time being. I'd prefer a url of the type [[login to view URL]][1].
