445385 Statistics and trend graphs (google graphs)

we're looking for someone to help us with automated exports and creation of graphs (Google graphs) from our database and present on our website. We have a real estate website and we're looking at creating graphs covering the city and different statistics like: average price in area, average price of 1 bed/2bed/3bed etc, average listings price condo/house/townhome, average sqm price/area, average price in building "xyz". Most of our listings come with longitude and latitude and we would like to create a "hot zone" overlay on google maps to see price ranges in different areas. These graphs should somehow be updated automatically or at least semi automatic by running a script that updates the graphs. No manual export to excel and filter and create different graphs. We should be able to save the last batch of statistics and make trend graphs. so for instance if the average sqm price was $1.000 last month and this month it is $1.100 we should have a trend graph showing a rising trend and this should continue over time. If we could have some "ready made graphs" displayed but also maybe a function with dropdown lists where we can choose the different details and it will show the graph for the chosen details it would be great. We will only consider programmers who has feedback and have been working with similar projects. Payment only 100% escrow. Questions, please use PMB Thanks
