Contact form

I recommend to learn PHP basics, just to understand who this language works. Scripts like contact form can be easily downloaded from the internet, e. g. from Hotscripts.

I recommend to learn how the PHP variables work, how does "echo" work a you will be able to customize any downloaded script.

However, as the Themeforest customer (I have bought two designs so far, but checked out hundreds), I would not expect working PHP code in the website template. In fact, for me it is better just designed contact form because I want to implement my own contact form script with my own spam protection. So maybe it would be better for you to work only on the design.
