Hi There,
I have done migrations from v2 -> v3 of Google Maps api prior. Very much an expert on Google Maps, as I have build several apps/mashups based on maps. Also experienced with other mapping packages like ESRI, OSM.
I am a US based semi-retired contractor with over 20 years of Wall Street Technology experience. I am quite interested in helping and it would be great if we could communicate on some additional details. Can you provide the URL of the web site?
Many Thanks,
Ed
