Make a simple illustration/animation/video effects for a website intro

I will supply you with an image/photograph of my signature; "Lachlan". I would like this turned into a quick video to be used on the front page introduction of my website. The idea is basically to make a video of the signature as if it was being written/signed with a pen. Starting from the left and moving across to the right. Video will be made on a white background with black font. It needs to represent my exact signature as it is provided in the jpeg image or very close to. The actual pen does not need to be shown.. just the moving illustration of my signature being drawn across the page and about 5-10 seconds duration.
