Small B2B telecom brand refresh

Hello,

I am looking for someone to help to redefine our brand without changing the logo, the name, or the colors. Yes, I know, it's not easy

The expected outcome is:

• Header image from LinkedIn
• Header image for Facebook
• Wallpaper for desktop and smartphone
• 3 sets of google display ads
• 4 different T-shirt and Hoodie designs
• 2 A4 print ads

I am not happy with our website and it might follow in a later project. Budget, I do not know... what is required.

The brand is www.mixvoip.com a B2B telecom provider.
