The idea may work for certain industries but in my experience and the hundreds of trade shows I have attended a large majority of exhibitors the information you truly desire is not visible to the typical attendee which is what this guide would be categorized to be. You need to be identified as one whom who is worthy of the best information or meeting with the right people. This would be a challenge, I do have some ideas on how to overcome this challenge as well as many others, give me a call and we can discuss.
