Drupal Module Expansion and programming(repost)

Drupal module functions need to be expanded . Drupal 6.2x. I need to expand the way that the [[login to view URL]][1] module works. It is a library catalogue module. It is a small module, but I require a few modifications to it. The work flow for the module currently functions as: Select Single Item (node) ->Select single Patron (user) -> loan item (transaction) I would also like the **function(s)** of: 1. Selecting single patron -> Selecting multiple items or single item (ajax or AHAH) -> loan item(s), have printable receipt of transaction. 2. View patrons current Loans -> select some or all and perform transaction on each item,have printable receipt of transaction. For example: select 5 out of 10 to check in or 3 out of 10 to renew. 3. Log all transactions, have printable receipt of transaction. 4. View all currently checked out items, and who has them out. Be able to sort by date out, patron, have printable receipt of transaction. You will need to be able to create _hook items in Drupal 6.2x, be well versed in PHP, and Mysql, and javascrpt.
