I am looking for a classified script that only the ADMIN can post to. I want to use it for displaying and selling stuff on line. Having integrated pay features is NOT a requirement, but would be a plus.

An example of the Photopost one is here:

This style is maybe a bit better for what I like, but I think it is custom made:

Can you recommend any scripts (opensource or cheap) that would enable me to display items for sale, customise the fields, enable searching of fields and can display more than 1 photo in each advert?

Thank you for your help and suggestions.
