Unwrapping 52 models is no small task no matter how easy it is. For proper UV mapping you'll need the front and back of the letter unwrapped and then the surfaces making up the letter "depth". Say 5 minutes per model is still well over 4 hours work and import/export, packaging it all up nicely for your use (exporting the layout as an image for guide use in Photoshop etc) I'd say 10 minutes a model.
UV mapping is not difficult, once you know how, especially if it's just "letters" rather than some organic model such as human or animal (which can be difficult and requires some artistic skill). What package capable of UV mapping do you have access to / knowledge of?
I could make you a quick tutorial on how to do it in Blender and I'm sure someone else could give you directions if you use another package to get you started. "Teach a man to fish... etc."
