Hi tryan,
I went through your requirement and the reference given.
As i could understand, you need one extra functionality to generate pdf and send it along two mails.
All the validation etc are completed already.
1. I have some question regarding this project like, is it a CMS or CORE PHP?
2. The confirmation page is already made, or we need to made it as well?
Well, i am available on skype (ID: megauravpanwar), and it will awesome if we have some words/chat there, regarding this project.
Best Regards,
Gaurav Panwar and team
