Link Exchange Directory solution + Advanced Directory with Item customisation


Among other zillion things, I’m desperately looking for a solution to:

1. Create a section on my WP sites with a directory that automatically verifies, check link exchanges, and notifies by email to the users (like PHPLD does but for WP). Since my plans are to create several directories, I can’t afford the price of PHPLD.

2. Create fields (taxonomies, custom fields or whatever) that signed users must fill, like amenities, photographs, various descriptions, and so on. Obviously, every site has different fields so I need an easy way to configure them on every domain.

Any advice or recommendation of the best path to follow would be greatly appreciated?
