I also have a consulting firm and we have just completed a series of maps (6000+) covering all TRI facilities in the US. These will be part of EDF's WWW scorecard project. Each facility is hittable. We ran into some of the same problems that you describe. The GIS we used was not programmable (also not arcview) so we had to output the image (*.bmp) and an associated data file that included the preferred latitude and longitude. We then developed an in-house program that would allow us to physically move and resize if necessary little boxes over each facility. The program then output a file with the pixel coordinates of the top left and bottom right of the hittable box. We then wrote another program that would write the html from these data and image files. Now that we have completed the project we are working on both of the programs hoping to release them to the public in a month or so.
