almaqalah.com wordpress spinner plugin

Hello, I need to create a wordpress plugin for my website service which rewrites Arabic articles. This plugin will allow clients to use my service on their wordpress based websites to rewrite posts, I'm going to create special API key for each client to allow clients to use the service for a fixed period of days or months. This plugin should include these options: - Auto rewrite future published posts. Yes/No - Rewrite published posts instantly. ( as soon as they get published) Yes/No - Rewrite post title? Yes/No - Bulk rewrite all old posts? Yes/No (there should be a filed to prevent certain posts from being rewritten according to its ID). - Words Not to rewrite. ( With a field that allows to exclude certain words from being rewritten ). There should be a button inside the editor to manually rewrite posts and show the result before they are published. Also there should be a count down for the client API to show how many days are still there before he needs to renew the service.
