I need a business logo created

I need a logo designed for a trading business. The business name is ( NextGen Trader ) I'm visioning black, grey & gold but open to other ideas. I want the logo to be readable and modern, I will be selling new and used products ranging from clothes to games, consoles and other electricals such as phones and tablets.

I will need the logo in JPEG, PNG & SVG formats as I will need to get it enlarged into quite a big size for the front of my shop and then for social media and heading purposes.
