I have an immediate need for a google maps developer. I need to create a map that has "multiple" GTileLayerOverlays - and is controlled via checkboxes in a form on the page. The PNG's are cut for the 2 GTileOverlays. As well, Javascript should allow the opacity of the tiles to be modified accordingly. As with all my projects, if you can complete this in 'record' time without sacrificing quality, then I will give a $50 bonus.
