When I think of a business that can handle that many demands, I think of a person or biz that is very efficient. I think of a real professional title, not a catchy one. You want to present a polished image, to attract quality clients. I would focus the name on the duties you would gain the most income from, such as event planning. You might use your city name (in my case DALLAS, TX) and call it your city name, plus Event Planner. Then list other duties on your business card and website, that you serve. Such as, Dallas Event Planner. Or if you want to sound larger, you might want to use your State name in it, as in mine: Texas Event Planner.

Best wishes! Alena.
