Advertisement Bilboard designs for New oppening Mobileshop.

I'm looking for a skilled designer to help me create eye-catching billboard designs for the upcoming launch of my mobile shop. The billboards need to be large enough to be visible from a distance, so I require them to have the dimensions of either A4, A3 or 6m x 3m. I have some general ideas of what I'm looking for but no specific examples. I understand that font and color choices play a critical role in capturing attention and would like the style to be bold, block fonts in bright colors. I'm open to creative input as much as possible so that the designs can accurately reflect my company's branding and message.
