how can i put it on the web where they can log in to an account and fill in the info and save and fill it in as they go along?

I doubt there is any website around that will allow multiple users to log in and save/edit the same spreadsheets but you want to just let your password be known by them then you could easily make a Google spreadsheets account. Another website you could try is EDIT GRID, it allows one person to have a account and make spreadsheets but for it to be public and allows everyone to view it without logging in to an account. An example of edit grid is HERE.
