Multiple Mailer Modification Request

[admin]

Can anyone please modify the following script so that it does 3 more things

1) Addition of following fields - Address1, Address2, City, Zipcode, State, Country, phone, fax
2) validates (visitor fills all the fields)
3) After submitting it should open a thanku.htm page


<FORM NAME="mailer" METHOD="post" ACTION="" ENCTYPE="text/plain"
onSubmit="(document.mailer.action += mailtoandsubject)">
