Theme Customization / CCS Help

Hello,

I’m trying to set my theme looking as this one: https://www.amersy.net

I’m trying to remove logo sign on top left and the menu button on top right, change the frame color to black and have social media widgets (buttons) right underneath the logo in the middle.

Theme I have: https://themeforest.net/item/9010-corporate-and-creative-theme-for-wordpress/10369678

Website I’m trying to set: https://www.joornbold.com

Would much appreciate any help!

Cheers,
K
