New to this

I am looking for all the information I can get. Is Indiana (Fort Wayne) area covered in this? My daughter (35 yr) is looking to get the message out that she is in need of a kidney transplant and we decided to look into the billboards

You should contact all of the billboard companies in the immediate area and see if any would take this on as a charitable cause. Most billboard companies are open to ideas on using their vacant space in a productive manner to serve the public good.
