Switch forms from Contact Form 7 to Gravity Forms while keeping styling

I have a site that currently uses Contact Form 7: [login to view URL] There are 2 forms currently in use: Newsletter Signup (at the bottom of every page) and a Contact Us form, which can be seen on the contact page and also in a popup throughout the site (on the home page, you can see it if you click the Request a Consultation button). The forms are highly styled. I need the forms recreated to look EXACTLY the same, but they need to use Gravity Forms instead of Contact Form 7. I need this project done in 12 hours or less. Thank you!
