Construction Plans for Residential Build

I have a rough draft of a two story, concrete slab home plan that I designed in SketchUp. I'll need the design to be finalized with construction ready plans. The overall layout is set with a 10' ceiling height per floor. The floor system is to be open web wood trussing (minimum 11 7/8 depth with 24" off center spacing). Roof is flat. This is for a Texas residential build and should be designed around the state's building codes.
