Help learning how to use different payroll systems

I need someone who can help me select a payroll system for my company. The freelancer MUST have access to at least one payroll system (e.g. ADP, Paycom, Gusto). I would like to learn the basics and also understand if it's possible to generate a few specific reports that I'll need to help run my business. These include: - Running an employee roster including contact information and direct deposit information - Batch uploading direct deposit and garnishment information to the system
