Schematic Design for Industry Standards

Hi there, I am only picking out the finishes for a four-story office building. See the attached. I will need the conceptual drawings so the customer can visualize everything schematic design and possibly even a video walking them through once I have picked everything up. Are you able to help with this? I don’t have a date yet I am in Houston Texas and I just wanna make sure that we can be able to do this. What would your fee be so that I can include it in my quote. Also how would you work.
