Professionally designed Animated App Screens for video/print presentation

I'm developing a gaming social network. This network will be used primarily for five things:

• Communication. Latest news, information, announcements, and opinion
• Gameplay. Finding people to play games online, in person, or at local business establishments
• Events. From professional organized events to spur-of-the-moment gaming parties or meet-ups, users can host, organize, and recommend parties and events
• Classifieds. Selling and buying goods and services, jobs, real estate rentals, finding roommate, dating
• Recommendations. Games, local businesses, experiences

I need to create approximately 10 screens that show the above functions, how they would work, as well as our value proposition. These screens would be used for presentation purposes. I want to create a an animated visual presentation, as well as a simple deck.

UX & Game Development experience a plus.
