Can anyone help- I need a cgi script that will email a PDF?

I created a PDF form that has a submit button. I want the filled out form to be emailed to me (in PDF format), but if I use the "email" submit button, users filling out the form have to have Outlook or similar to send the form (it doesn't work if they only have webmail). I want everyone to be able to send me the form without having any special software, so I am going to have it upload to a folder on my server when the user presses submit instead. The problem is, I don't know how to write the CGI script that will then take that form and email it to me. Can anyone help me with this? Thanks!
