I wouldn't go the "employee" route, as I've had businesses utilizing both employees and IC's, and I worked as an IC. There are inherent risks having employees.
The first and foremost is "liability" for someone operating "sight unseen". I don't know if he or she be driving around seeing customers. checking on wedding sites, but as an employee, and when they are even driving their own car on while employeed, during business hours clocked in, as an employee, if they run someone over injuring someone seriously, on he job, you are on the hook. That's why one of the first questions the insurance company would ask in an accident case is "what were you doing at the time of the accident". If he or she said they were on assiginment, during working hours, then, you're on the hook.
I had an employee, would drive out in a customer's car during business hours, to test drive a car, then visit a liquor store, buy a bottle, have a few sips, then drive back, and stagger out of his car. I did not see this, but a local neighbor pointed this out to me, we kept an eye on him, and soon enough, the following time it happened, he was told he'll be fired the next time, and he was finally fired. I cannot have an employee drinking and driving during business hours. How can YOU be sure your employee who clocked in, is NOT having a beer or two for lunch, and then drive out while clocked in, even to "get a burger"???
With employees, in my state, I also get stuck paying "unemployement insurance", though I never had seasonal employees. With IC's, that is not my concern. With an employee, business slows down, I lay him off, he collect UI, my rates go up.
With unpredictble revenues, getting bogged down like this is not a good idea.
I'm glad you won't have employees working in your home, because if something happens, your homeowners liability carrier won't be too happy with someone operating a business out of a home, and would deny claims if anything happens. I partnered with someone doing business out of his home office, where I worked several hours a day, and he made sure I'm an IC, not an employee. If I was employed and worked there, got injured, his insurance company would have a big problem.
Employers are held responsible because the employee is under your control. In your case, making the assistants an employee, they are not under your control, yet you're still held accountable.
