Word press, Mambo, what is the right for me?

Hi there.

I have the need to create a catalog of service providers for my office, and I do not want to make it from scratch (since there are many useful options out there). But I'm not quite sure which option to pick.

I just need to create a list of service providers (like 250 of them) and store them so I can sort the acording to it caracteristics (price, format, contact, etc.).

I also need to create some catalogs so I can normalize the characteristics like formats, schemes and so.

What is my better option to do it so?

Thanx for reading, any help will be useful.

Best.

Please, if I'm posting this in the worng place, tel me know.

Best.
