Need a Mid laner and Support for a 16 week tournament team

So me and some buddies are planning on competing in a 16 week Tournament. This means every friday we compete in a tourny for a league and the top 8 teams will go to finals at the end of the 16 weeks and compete for a crowd funded cash prize. I need a mid and support plat+. Please let me know because our first tourny is tonight and we need to get a little bit of practice in before we play.
