Only following pages are missing: 1) saving all last will documents + personal data 2) paying buttons + success pop-up + admin control of payed periods 3) relative contact + login information + email login password assignment 4) relation login + email login password assignment 5) Listing pages where visitors can look and search.

I think a good coder has better ideas for some issues. I'm a newbie with WP. What I need is a coder that can help me trough this project and make it a success. So I hope you're creative and flexible. Then it will be a good project for both of us.
