What needs to be done:

1. Set up logo (default, sticky header, mobile - both default and retina)
2. Set up favicon (favicon, apple iphone upload, apple iphone retina upload, apple ipad upload, apple ipad retina upload)
More on sizing and Avada logos, please Google google "avada logo size"
I have PSD, PNG and JPEG source file of the logo which I will provide you.
3. Set up logo in footer
4. In the footer, at the very beginning of the footer, I need you to put small USA and EU flags on the left and then, text: Radionics.Shop Is Euro-American Entity Found By Master PlutoCraft Serving The World!

5. In the top of the header, change contact into text to gold and set up woocommerce items (Shopping Cart, My Account) to match menu look (gold text, black background, gold separators). You must also provide me with a way you did it so I can modify it in the future if needed.
