Website/template screen captures

We need 12 screen captures of your previously designed websites (in 2 sizes) or templates. We would like to display the screen captures on our web design page as examples of work we can do. Please do not bid unless you can actually provide us with the screen captures and provide a price. At the moment we have 12 screen captures of nicely designed sites (see screen capture) on our site but due to legal reasons we've been told to remove them, so your supply of 12 screen captures will replace the current portfolio. The screen captures must be slick/nicely designed and impressive. We want them to be preferrably in different sectors (for example: sport, business, education, medicine .......) The screen captures must be yours and we want that confirmed in writing. The provider will also get our first choice for outsourcing web design jobs, which we are increasingly getting. We will need to see & approve the samples and if we like them, Payment will pay you immediately after delivery.
