Simple Wordpress plugin

I need a very simple wordpress plugin created. The plugin should be able to delay the main content (posts) from showing up when the website loads. For example, you go to [login to view URL] and all the sidebars, headers, footers load first, but the plugin will delay the main content from appearing quickly. In the plugin settings, you should be able to input a specific time-interval in seconds, to delay the main content from showing up. (please see attached image for example of how it should work) The plugin should work on most wordpress themes without doing any modification. ## Deliverables If possible, the main content should appear with an effect (like cascading, blinds, fade in, etc.), These effects should be in the settings options of the plugin, in the administration panel. Effects are not mandatory, but a bonus can be paid.
