custom marker icon for google maps

i need a custom marker icon for google maps just like the png file with the "MAX" logo attached. my logo is also attached as photoshop file with transparent background (i can also send a vector graphic later if needed). here you can see the demo marker? icon? in action: <[login to view URL]> what i'd need is to have my logo put on some "white plate" just like the max logo. it should look about the same and have about the same size, but of course the shape of the plate would be different. i need some high quality look of the marker, and the deliverables should include a layered psd file and a png file just like the demo file attached. the png file seems to have some "partial transparency" at the edges? to allow smooth integration into google maps - my png file should integrate into google maps just as smoothly. shadow file? is not needed - just a clean and cool looking marker icon with my logo on it. this shouldn't be a very complicated task for graphic artists, but it's not what i can do on my own easily. please let me know if you should need any further information. thanks a lot. martin.
