Quote/Calculator with Paypal payment

I run a publication and I am trying to create a quote/pricing section on a page but can't find a plugin for one, any suggestions?
It needs to be similar to this
http://www.yourcallpublishing.co.uk/advertise-with-us/advertising-calculator/

But also,
allow people to put in their details/contacts
and once it calculates let them purchase through paypal

Is this possible? if so - what plugin would be best.
