Google Mapping work - Geocoding

Hi, I need Google Map help. I have a static vector graphic map made in Adobe Illustartor of a small city featuring neighbourhoods, coded in diffrent colours, according to profession+income. This should be imported/made into a Google Map and with some minor interactive features. I started to do this by typing one by one, but its taking too long, and if someone knows how to import the, it would be much quicker. There are 175 different neighbourhoods in all so hand typing is not impossible either. The map shows 4 main professional groups in different colour, and fading colour groups according to average income. Show on map on neighbourhood click: -Area name -Percentages of different professional groups (4 different professional groups, colour coded) -Average income of area The data of professions and income I have is in excel format, but its not ordered correctly, to be directly imported into map as comma separated file. What Im after is much like this google mapping: [login to view URL] Let me know if you can do this!
