need a wordpress plugin to be made for a wordpress website.

Hi, i want a pluging that should function in following manner. 01. I should have an option to give a directory to plugin. 02. All posts should be saved as .html file in the directory instead of saving it in the database. 03. No posts (only Posts) should go to the databse. rest no any functionality should altered. Listing of posts must be as per the them choosen. My suggestion is save the name of the .html file and the directory as well and fetch the content of the html for the user view of the page.
