Need PSD for making themeforest html template

From last 14-15 month, I am learning front end development. now i am being able to do any design. now i want to submit some html template in themeforest as my portfolio. so in need nice psd. how to i get the psd?

psd is the format in which photoshop saves projects
so you need Photoshop, and different skills - creating a design for a page using a digital image editor is completely different than creating a page using html and css

thanks for your replay
