create easy iframe contact form.

I jsut want to use this one: [login to view URL] "The 3rd one: A simple contact form with fields: Name, Email, Phone number and Message" It's so my client can put it on his site or any site and he'll get emailed. I may need to add new fileds to it, but not sure what. I'll pay $15 for this. I think it can be done in 20 minutes time.
