help with coding plan of attack

Hey all, If anyone could help me with the task I want to do I would greatly appreciate it. Below is what I am wanting, can anyone help with how to go about this?

So, the user will enter a new Job. Under the Job I want a Equipment "template/list" that is in a winGrid (At the moment) connected to the SQL DB. I envision the user making this list at the beginning. Then each day, the user can pull up what was previously entered, and make changes and save AS NEW rows in the DB.

I don't want them to keep pulling the previous and just updating it. I just want to take that List of Equipment (originally stored in the DB) and throw it in the dataGrid, that way they can put different info (ie: hours, date, etc) in the other fields and save it as new rows in the DB. I need that list for each Day.

I'm just working on thinking/coding this through right now. Does anyone have some suggestions or experience with something like this? maybe storing that list in a external file on the HD would be easier that using what was inputted in the DB previously? Thanks for any ideas, forseen problems, etc. :ehh:
