WprdPress Plugin - small customize

I need to customize a WordPress Plugin. Function of Plugin: Insert 2 Plugin Shortcodes (start and end) into a Page or Post. Between the shortcodes put in any content (picture, text...). Visitor see than a picture "Click Like to see the content". After he click "Like"-Button, he can see the content! Thats it! Customize I need: 1. The plugin choose automatically the page to like where the shortcode is insert. I will put in the page in a field which the user like. In some cases the Plugin is insert not in the frontpage but I will that the Front- or HOME Page is liked! 2. I will that the Viditor who clicks on "like" directl with this one click post a message on his wall! This feature is inside the plugin but only when visitor comment it! I will automatically! For a good developer ist a simple thing! The whole Plugin cost $17...I don´t pay much money for this small customize! Please think about that when u bid!
