It will surely depends on where you are located. In Canada, you can ask the 2 employees/contractors to provide you a bill like any company does when they sell services to customers and you can pay them by check. The employee/contractor would need to be registered as a company (incorported or registered on their names, it doesn't matter). Expect to pay sales taxes if you go this way but you won't have any "employee paperwork" to do.
