Credit Repair Membership site

I am looking for a credit repair software package that can be intergrated with my Wordpress membership site. The client will need to be able to log in and track their progress via an area where they can customize sample letters and print. Also area where tracting their progress of cleaned and un cleaned accounts as well as make notes on each account. A calendar is needed to tract when letters were sent out etc. This should not interfere with other membership script actions.
