Vista - power shell for add OU, sub'ous, and users to domain from file

On new AD, every night, one external database send to AD server one .csv file
with this structure:
username@xxxxxx, name, surname1, surname2, OU-firstlevel,
OU-secondlevel, OU-thirdlevel,change_password(yes(1)/no(0)), password
Example:
user1@xxxxxx, mark, smicht, lock, EE.UU, Carolina, HR, 0, oldpassword
user2@xxxxxx, peter, alvez, gonzalez, Spain, Madrid, Sales, 1,
newpassword
...........
...........
up to 5000 users.

Does anyone know of a website where there is a script to do this (or similar)?
Must apply for the initial load of users and OU's and the daily maintenance
of the AD with this file. (Every day new file, with few modifications)
EVEN I like rewrite with 2 moths more expiration date account if one user is
in the file.
This way, if the file remains the user (active) does not lapse, and if not
will have 2 months active (from the last time it appeared), and then
activates the account expires.

It's essential the OU's, and sub OU's creation, and include every user in
their respective OU.


Thanks.
