Short answer: business

Long answer: The high-paying in-demand jobs mostly fall into four categories right now: business, technology, engineering, and health care. Health care would be the toughest switch for you from where you are right now as you'd nearly have to get a 2nd major to get into a grad program there. Engineering would probably require graduate school since your degree isn't in engineering, and I'm not sure how easy it is for a non-engineering major to go that route. That leaves business and technology, and just a rough guess from your description is that you would prefer business to technology. You would most likely either be working in finance, accounting, or data analysis. A lot of this is just doing basic work with excel spreadsheets all day long. Those are the types of jobs I would recommend looking into.
