small modifications on existing Wordpress plugin

1. i have a listing directory plugin, not all of the data submitted are shown in the backend, i want to show these info in the listing page , there is a specific how to do it in the listing page, i really dont have time to do it, 2. i need to install a good plugin to add some extra options in the search (i will need a search by field kinda search to start working and put some exta options on the search filters) 3. fix an error "An error occurred in the upload. Please try again later." when uploading images or any other attachements back end or front end i have tried disabling and enabling all plugins... tried some hacks... no time to fix it (this was working fine 4-5 days ago) please only people with php and wordpress knowledge, that can start NOW!
