446045 PHP Email Script

I have a simple script which I have created in PHP which allows someone to send an email online. The fields they have to fill in are: 1. From Name 2. From Email 3. To Email 4. Message I want to add the following functionality 1. CC,BCC 2. Upload an attachment 3. Ability to enter the message as html if desired 4. Ability to enter several different email addresses in the "To Email" and for it to send out a separate email to each person Please note, that I don't want to use any external modules or anything like that. Please be in contact via PM if you are going to make a bid.
