Create images to illustrate our Home Page

We have a website at http://www.librelio.com. We want to change the images used to illustrate the home page. More precisely: - we want to replace the image below "Content-centric branded apps." by a slide show with 5 images - we want to replace the 2 images at the left of "Leverage your contents" by 2 new images. So that's a total of 7 images. We have the following expectations: - use some screen shots of our apps, inside (a) tablet(s). The tablet image can be either a photo, or an illustration (as currently). There can one or more tablets per image - provide images in the right dimension: they should fit in the current 2 areas specified above - include transparency, so that we can change the background of the site later if needed In order to show that you have read and understood our requirements, please start your bid with "hello from ..." (add whatever you want after hello from: your place, your country, the Moon...!) Optionally, we will appreciate if you provide 1 image for us to make sure we agree with your vision.
