Facebook cover image + Letter head redesign

Hi, i just need an facebook cover image by following design procedure. The landscape image should be an actual image - high-tech - representing the main segments we work in: Healthcare, Military, Automotive, Public Safety, Retail, Logistics. Maybe several images combines under the same look (color effect) that displays emotion, tech, etc show me with the facebook page how it looks like with facebook DP+facebook cover image. The square image should be the logo with blue bars on full black background. And one letterhead redesign , we already have an letterhead design just a few changes in the design as per the following request. The letterhead should be modified: - emblem should look like it's on a piece of paper dropping from the top right aligned to the text, and with a slight shadow to show it's on top of the letter. The spacing between the emblem and the end of the rectangle should be proportionate, like 1/2X or something like it - Contact info (Company name, address, email, phone, fax, web) should be per our web. And below a very fine line horizontally that sits on top of the text and separates from the letter text. No logo there - No watermark Thats it. More design work as follows: powerpoint templates, banners, tradeshow booth, etc
