(1) What is the name of the profession that...?

Interior Designer. Depending on where you are going to be building/drafting your designs, will depend on where you get your certifications from state boards, and such. You can start at a community college or a university. I know my professor went to Florida for her grad school. I don't know if it was Florida or Florida state, but there is a really good Interior design school in that state. It can take up to 6-8 years depending how far you are in college and if you have prior experience. Look at local businesses, and see if they are looking for entry level positions. If you can get your foot in the door to one of these firms, then you are almost a shoo-in. There is a ton of programs as far as CAD goes for interior design. For one of our clients, we used a First Person Shooter engine to create the proposed building that we were trying to get the building contract from at the time. CAD speeds up the process, but I do regret the day that most of us switched over to virtual from the good old pencil and parchment.
