WordPress The Events Calendar Pro expert needed

URGENT! Looking for someone who's worked with The Events Calendar Pro extensively. In particular, I am trying to filter the [tribe_events] shortcode or use tribe_get_events() function to create my own query and shortcode. I have had success with a few customisations but need help as I am on tight timeline. My goal is to display latest x number of events. If there are no upcoming events, it should show the latest past x events. It could also show a combination of upcoming and past events, but basically it needs to show the latest x number of events. Preferably we can filter [tribe_events] shortcode so that the DOM markup is the same as the plugin. If we need to use a custom query, that's fine, I can write the output markup. I am ideally looking for someone who's already written the same or similar filter or function and proven it works. I'll also share my code with you so you can help me debug. Thanks!
