Offer- and search-marketplace for users to register and enter their offers / searches?

Hi

 

Is Elgg the right application for me?

 

I intend to design a web-database, where user can enter and edit their offers AND searches. An admin activates these entries and changes. The users shall be able to delte their entries.

 

Searchable with multiple fields

Sorting

Option- and checkbox-function

 

I am no Programmer, but a power-user, with some experience in Joomla, phpBB.

 

I am looking forward to receive clear answers, and / or recommendation if there is a better suiting php-sql-solution, also for free or reasonable cost.

 

Sincere

Klaus
