Anyone know a good open source script I can use or work with for the following project:

Need a container tracking script - where admin can set password for companies to log in and view where/when their containters have been dropped off and where/when they are to be picked. -- Basic tracking sytem type thingy.

(1) Admin sets passwords for all clients
(2) Client logs in to see where all their containers are and when the due for pickup - basic tracking of their inventory of containers

I am having trouble finding something close to work with and dont have time to make the thing myself as I am still learning php.

Any suggestions appreciated.

If someone can whip something like this up for me in a day I could also send some cash - need it fast-- send me email
