Don't do it. Go with contractors. Here's the thing: a contractor is running a business, just like you are. If you don't work with them any more, they are not out of "a job." Their livelihood is no longer your responsibility. You are only responsible for paying a set amount you agreed for specific work. If they do not deliver, you do not have to fire them. If you can't afford them any more, you do not have to fire them… you simply don't renew a contract. If it turns out you don't like them, you do not have to fire them.
With contractors, you can also afford to try lots of people without disrupting anyone's lives or running out of money. You have freedom and they have other clients.
Firing people is the absolute worst, I can tell you for a fact… and I'm a person who fully embraces difficult experiences and has no problem admitting when she's wrong.
Even if you want to keep the employee (and based on what I learned & then heard from EVERYONE, the chances you'll keep your first employee are about zero), you will have a hard time sleeping at night because they depend on you and you may find your whole job becomes ensuring you earn enough to pay them. (A good rule of thumb is that you must have at minimum 150% of their salary on a monthly basis. More for non-US countries.)
People will say xyz about contractors -- they're not invested, they have other pots on the stove, blah blah blah. The same is true of employees, but they are harder and so much more painful to get rid of, and it hurts them a lot more. The trick is the right people. Finding the right contractor is absolutely possible, and it's much less stress to be wrong than it is when you are wrong about an employee.
For one, you can hire people for small getting-to-know-you projects. You're not going to find it easy to do that with an employee. Moreover, once a person is an employee, their behavior may completely change… being employed (and being an employer!) brings out all kinds of crazy psychological crap you never would have believed possible.
So, yeah. Don't do it!
