IPhone & Android App for Music Venue

I am a marketing director for a live music venue in Fort Worth, TX. We feature live music from Texas Music Artists/ Red DIrt Country Music. I want a sophisticated, well executed, and professional looking app for IPhone and Android. I do not know much about building applications, but I would think that what I am looking for out of this app is fairly simple. I want to app to hold information about upcoming monlthy shows, drink specials, phone numbers, emails, website, and VIP membership information. Therefore I will need someone to be able to update this app once a month, unless there is an urgent change needed. My reasoning for wanting to do this is that it gives our customers an even easier way to get information about the club. Again, I do not know much about the specifics of building an app. If you think you can do this, or be interested in working with me, please contact me. Thanks!
