Payroll master files

Has any one had custom programming write a import utility for importing
payroll master files. Including emp. master, tax tables, deductions,
classes ect. If you have please let me know then maybe I can get the same
thing from epicor. I have just been given the task of moving 75 employees
from one company to another before Jan 1 with 4 holiday days in between.
Help!!!! If you have any input I would sure appreciate it. Are there any of
you third party programmers that could write this or maybe just changing the
company name in the employee master.

thanks
