Im looking for a way of going to my wordpress site, logging

Im looking for a way of going to my wordpress site, logging into a specific page with a username and password, and then having a page that lets me select a clients details, and then create a form that lists work I have done for them, so it can be printed off and then signed. A copy of the form should be kept on the wordpress site and be available in the future f needed to check on things. Its a poor mans tech-support page Im looking to create, does anyone know if there is anything like this around?
