Database Creation by Tayloring Clubdata (sourceforge project)

I need the open source application clubdata (can be found on sourceforge) tailored to my non-profit organization's needs. My organization is called Locksport International. We are an organization that promotes the safe and exciting hobby of lockpicking. We are also a competitive organization that compares times and difficulty levels of different locks to see who is the best lockpicker :)We need a database that will allow us to keep track of basic members (by taking advantage of what has already been created by clubdata) AND another portion of the database that can keep track of each members times on certain locks. In addition to being able to record times and attributing those times to certain members, we would also like the ability to create our own parameters in the database. For instance, if we got a brand new shipment Locks that are not in our database, we could add those locks into the database along with its difficulty level (and other sub attributes). That way we can immediately begin recording peoples times into the database without having to internally edit the database to add another parameter. With all these new parameters, we would need a new search function for each parameter created. So if we add a new lock into the system, we will need a new search function that will allow us to compare times on that new lock. I also want to be able to have a "rank" attribute of each member that is calculated by the following: 1) Dividing the dificulty of a lock that somone has picked by the time it took them to pick it. 2)Taking a sumation of all the scores on on the locks that person has picked. (Disregard Locks a person has no recorded time for) Those calculations can be computed constantly, or by pressing a "calculate" button. (no preference) Then we will need a search function for that parameter as well. I hope this is clear, thank you for your time.
