Get your hands on photoshop or GIMP and this this is easy work. If you can get ahold of the text file and install it on your computer you won't even have to use those images either. Websites like dafont.com may have something similar. The more complex graphic design programs should net you an alpha layer making the background invisible when you add your text.
