need help with code modification

[MyChildCancer]

Hi,
I am looking for someone who is willing to assist with some or all of the following issues which apparently require some code modifications:

When setting User Profile fields:

1 - Add another DOB field (with a calendar to choose from and an option to show an exact date or just age)

2 - In the "Referrer" field, a new user doesn't always know the USERNAME of his referrer. How can I enable registrants to enter a name instead?

3 - Highlight the "must" fields, by adding a small asterisk or coloring them in a different color.

4 - Remove the DTS option from the Time Zone.

This is for an important cause. Any help will be appreciated.
Please PM me.

Thanks,
