Or any number of products for a myriad of uses, limited only by your imagination. We highly recommend the CD-ROM format. That way, you don't have to pay for disk duplication for both platforms.

If you owned a mortgage company and needed to explain to your clients how to get through the maze of buying a home, you could do so most efficiently with an interactive digital brochure. Take your clients step by step through the maze. Include all the forms your clients need and make them printable. Run a video of your mortgage processors giving clients tips on how to make the best application.
