Update logo and letterhead

We use a logo for our business that was selected from clipart many years ago. We really like the logo but need it to be personalised and a little bit more inclusive of what we do. I need a new vector image and jpeg image as well as a letterhead in Word format similar to the one provided. We ared based in Swaziland but operate throughout the region and distribute media products such as newspapers and magazines. This can be incorporated if desired. The letterhead must include all details as per the sample but fonts, colours and layout may be changed (Bear in mind that our letterhead is often printed in black & white though). All contact details must be editible in case they change. I expect a basic mock-up in PMB to be able to make an informed choice. Payment will be made after I receive the requested files.
