Need a consulting page and store data in database - Joomla! Forum - community, help and support

hi,
i have modified database table jos_users , made changes in few of files add feilds in registration form. (based on tutorial provided in http://www.dart-creations.com/joomla/jo ... -page.html)

now want create consulting page should see if user loggedin should relevant information (username, company name, sector, description,etc) displayed onto page , input box submit further queries.

and if user not logged in page should show text explaining purpose of 'consulting' page , loging module should displayed.

i not able how proceed in doing same.

i thought should create new table in database storing consulting needs. table linked jos_users table. when user fills registration form user information stored in jos_user table , consulting need gets stored in new table against corresponding user id.

can me out or provide me links how should proceed. link relevant tutorials of great help.

core hacks never idea because upgrading version may overwrite hack.
there may other un intended consequences well.
your best bet create component links joomla user id it's own table of desired expansions.
