I really need a profile search

with customizable search options

that have been previously selected by user to customize their listing

and was mandatory when signing up in questionaire

so I can have guests come by and search the directory of profiles and
view them and maybe even comment on them

with posting only upon profile owners approval.

All on the main page without having to be a member and withpout giving access to anything else except profile and comments on profile. Any siuggestions on how to accomplish this?

Kinda like a dating site would have search on front page and let you view profiles and maybe a comment but nothing else without joining.
