Copy Writing for payroll service

I need someone to create a series of postcards that market payroll services. I have some basic ideas on copy but need a professional writer. The successful winner will make four different postcards with copy, graphics and layout designs. Must use correct English Samples of your work is required. My employees came up with a series of ideas about our payroll services. I have attached a file with the list of ideas. These are just some notes about our services. I don't want the copy to say what I can do for the client. I want the copy to explain what the client gets for using our service. The main reason to use my payroll service is because I am an accountant and I see people missing out on tax credits. That is what makes me different than other payroll services.
