Contractor payroll services

I'm about to cut the agency out of the equation with my long-term contract (2 years so far) and reduce the amount they're taking from my wages. I don't want to avoid tax, don't particularly want (or really have) deductions and don't have any other significant income sources, so the company formation route isn't a good idea. I just want someone to do my payroll, insurance and super.

So can anyone recommend such an agency in Australia?
