Dynamic heatmap for google maps. Need google maps GURU

I currently have a website that uses google maps to display the location of images on a map. The website is written in Classic ASP and javascript. Currently whenever we have more than 200 images in view we display a pre-rendered google maps tile overlay that shows a heatmap of where the images are clustered. You can see an example here: http://placesnap.com/snapmap.asp#Geo=35.1288943410105,-120.4595947265625&Time=All&Zoom=8 The only problem with this method is that the images are pre-rendered. I would like a dynamic heatmap that can work with Markers to display heavily filtered results. The database may end up having millions of points of data, so the heatmap does not have to take every point into account. Just enough so that it looks good. For instance it can get the first 2000 points within the current view that meet the current filter. Then it runs some clustering code to find areas of high concentration. It builds a heatmap based on different colored markers that either look like semi transparent squares or hexagons that give a cool pixelized look. This heatmap must run quickly for the user so we can't display too many markers on the screen at once. I will have lots of work in the future and I reuse the same people over and over if we work well together, I am looking for someone that I can build a working relationship with.
