Simple Variations to an Existing Business Logo

Very simple project, should take 1 hour or less. Our business has an existing logo which consists of an original image combined with text (the business name). I have this logo in several file formats: AI, PSD, JPEG and PNG, and I will provide you with all of these. I need two things: FIRST, simply add a ".com" to the text, in exactly the same style/font/color as the original, and return this modification in all of the same file types. We just need a second version of the logo for our online business. SECOND, I want a 3-D version of both logos (with and without the .com). There is a particular 3-D treatment that I am after, and I will provide you with a sample of this effect. (I am not sure, but I think it is a standard Adobe effect.) Looking for someone with experience in Adobe design tools. I NEED THIS QUICKLY, within just two days.
