about PHP

Hello, my name is Gustavo Padilla, I'm working now in a Chilean Oil Company's project to migrate ASP systems to PHP. I studied the PHP homepage but I found nothing about how much does PHP costs or if there is any option for paid support or about the licence. Please I need to know the real price that I must pay for PHP to include it in the project evaluation. All information concerning to "the money part" will be very useful for me. Thank you very much, Gustavo. _________________________________________________________________ Charla con tus amigos en línea mediante MSN Messenger: http://messenger.latam.msn.com/
