Need replacement # boards and custom decals made for an MTH AC4400

I have recently purcahsed a MTH SP AC4400 from a fellow forum member. I am planning on making it into one of the UP "patch job" paint scheme locomotives (when UP aquired these from SP in the merger, they put the UP shield on the front, painted over the old cab # with UP yellow and renumbered it w/red #s, and changed the # boards to match the new cab # -  pic below). I figure with 3 decals, and 2 number boards, The look I'm shooting for will be accomplished. That being said, any suggestions where I can get some number boards and/or decals made? Any help would be greatly appreciated. Thanks!
