Banner Design for Facebook, Youtube & Mailchimp.

Design details: Production of 3 similar banners purposed for FB, Mail Chimp & Youtube - (size and details included below).
Banners need to be crisp, eye catching and clear. It needs to be clear visually that we are company that produces video (camera, video wall) and our new marketing slogan is 'Be SEEN in 2015' encouraging companies to invest in their own marketing

I have included a sketch, this is for content and a general idea (The Strange looking thing of the right hand side the front of a camera with a matt box!) - it is not a template to be copied, I need your design input, that is why I am hiring you :-) Whilst I have provided the ingredients, I need you to make it work visually, and am willing, for a good design to lose some of the suggested elements: It is about a dialogue between us to ensure the best design.

Needs to include:
1. the text:
Be SEEN in 2015
Contact us today to discuss your corporate video requirements
('Be SEEN...' , much larger than 'Contact us...." suggestion to relative sizes below)

2. Camera or lens - right

3. Video wall, bank of screens suggestion or motif.

Logo (doesn't need to included), but attached for colour reference.
