Hi
I've been asked to develop a booking system for a delivery company.

They deliver products from a list of 25 fixed locations to and from any address within 10 specific zones.
There are 5 classes of delivery, going all the way from basic to 1st class.


Prices are based on
zone they are coming to/from,
endpoint they are going to/from
class of delivery


I'm considering populating the database with all the combinations of these three pieces of information.

If there are:
25 endpoints
10 zones
5 delivery classes
that makes 1250 records (25x10x5).


I'm wondering which would be easier way to implement this.

Hacking the existing product-type code in the 1.3.7 codebase, to display the correct information at the appropriate places
OR
implement a new product type (either from scratch or hack an existing) which would specifically fit out requirements.



As I'm thinking to implement this job in Zen, I'd would like some feedback or suggestion.

Any help would be appreciated.


PS) Obviously we would have no need to implement a delivery charge.
