Google API v3 - Custom markers

Anyone have experience here? I'd like to upgrade from APIv2 to APIv3 and have edited colour and size of map, but having trouble figuring out how I transfer all my custom markers to the new version.

I'm not going to pay much, but if you can point me in the right direction for a few bucks I don't mind finished the grunt work of copy and pasting all the code.

Please feel free to contact me via skype, Thank You!
