Simple animated GIF required

I require an animated telphone number gif - I would like it to look something like the telephone number on a particular site. All we need to do is a have a rolling animation where each number is highlighted in sequence. The gif will be 185 x 48 and have a background of #3d3d3d - the foreground colour of the tel number is white highlighting in a shiny colour. Please bid and I can provide the example I want to replicate and the actual number. Thanks
