Adapt Logo for Twitter, Facebook etc.

Our online web shop is beginning to market on social networks, particularly Facebook and Twitter, but with a consideration to expand onto others. We need our basic logo quickly updating, incorporating product images or other, to be more appropriate for this application. Required: 1 image for Twitter profile picture, 1 image for Facebook profile picture, sized and arranged to the respective dimensions, with the logo, or excerpt of the logo (at your discretion) remaining clearly visible at the common resolutions/display sizes of those sites. High quality photos and rendered graphics can be found on our website in Plastic Ducting, Grilles - Stainless Steel and Ventilation - Heat Recovery, these would be useful to visually communicate our types of products. Again, to be used at your discretion. Successful completion of this project could result in further graphical work for us. Please note: a quick turnaround and competitive price is required. Only two images as detailed above.
