Greetings! I would like to point out that the reference pages given in your posting do not have any flash banners.. The slidingbanners found at those pages are jquery/HTML sliders.. However, I can develop for you same banners using either flash or HTML5/JavaScript. You will be able to add remove content easily byeither editing an xml file (incase of flash) or HTML/PHP code in case of (HTML5 slider). If you like a backend where you can add./remove content, I can also make that, You may look into my feedback for total client satisfaction. ..
My bid is likely to change once I have more details..
Also please note, I am offering you a rotating banner/slider and my offer does not include doing any images for the slider.. you wil be providing all images to use..
Thankyou
