What is the best way to attract business persons to listen to an innovation in their line of business?

Question

The business is slum rehousing and neighborhood regeneration. It is also about getting shanty dwellers into the mainstream of asset owning and home owning.

Answer 1

make a project report and approach builders of high repute and government agencies in this department

Answer 2

Networking will be the fastest and most effective way to get the word out. Put together a pamphlet with hard numbers (if you can) and get out there, talking to them face to face. Ask anyone you know that may have any hint of a lead and then get in touch with those people. Also, Craigslist is a highly-visible and free medium for announcement. Good luck.
