Try a graphics program like Corel Draw. If the type and images are vector they'll be a smaller file size than scanning and using them as a raster image. It will also be easier to control the scaling. Once you get into the program, you'll find you can pretty much create whatever you want.
Once you print them out via color laser or inkjet on white paper you can copy them as you planned to.
3M used to make a product that by using a uv exposure table and some negatives you could make your own dry transfer material. It was pricey but worth it considering you could make whatever you wanted. Lots of chemicals and you needed to shoot film negatives of stuff. If there are any old school graphic artists out there you might remember a similar setup in your art department.
