Classified Ad Script to hold and import 1,000,000 Listings

A classified ad script where I can import 1,000,000 listings. would prefer the features of [login to view URL] (which is working like crap on my site) I have tried this twice now two scripts and a programmer and still do not have the issue solved. ## Deliverables A classified ad script that allows me to import 1 million records into main categories/sub categories - features like [login to view URL] nbut a program that WORKS and allows me to import the databases from CSV files and others to post their listing for free and a price. english only needed.
