Another option for you would be to order a helmet from a place like "saferacer" dot com. They have an extremely lenient return policy and great selection. I had sent back 4 helmets of various brands, then sizes, before finding the one the fit me the best. If the local brick and mortar stores have the same selection, then obviously that would be your best bet.
When it comes time to get your helmet painted, you may want to talk to Tyler at Censport. He painted my helmet and is currently painting my wife's helmet. He is considered by many to be the best in the industry and is usually booked up months in advance with helmet painting jobs.
Here is a link to a thread that shows pictures of my painted helmet.
