Professional company branding design required

Design details: I am looking for someone to redesign my existing company letterhead and also design a logo. I would like to keep the same colours blue, orange and silver but would prefer the colours to be more vibrant. You will see in the attachment my previous stuff is not eye catching enough.

I will also have a 42”/50” TV displaying products at the shop front I will require a 5 x templates that will have my company information and space for me to add products and prices. The different templates should vary but still keep with the company colours. I will be putting this template on a power point presentation so that in can loop throughout the day.

Points of what I else i will need to be designed and to match

Company name
Address & contact information
Logo to be an abstract mark
Letterhead with all of the above designs (one version in company colours another in black & white)
Business Card
Messages to communicate through the design: Previous works on a blue backdrop with orange and silver writing. I would prefer it on a white backdrop and implementing the 3 colours into the wording.
Ideas for the visual style: Clean clear & visible
Where the design will be used: Print, TV display
Extra notes: I would like samples of your previous work and a short description of what creative expertise you can bring to what i need.
