2 Php Forms with Captcha

I need to specific forms to be created, and I would like all of the code to be contained within one file (other than captcha info). I want it to be able to reside on any site I create, with the ability to send to more than one email address. One form is simple with the fields Name,Email,Telephone,Comments/Suggestions and the captcha field. The other should have Name,Email,Telephone,Year,Make,Model,Date,How Did You Find Us (Drop down),Please contact by (Drop Down),Services needed, and the captcha field. This should be be coded in php.
