Could someone paint my stainless steel flask?

I've talked a bit about a small hip flask I bought on eBay that I wanted to try and preserve.

I took the cheap pleather cover off it, but hate the look of it now, and the fingerprints on it, so I've decided I would like it in black.

Could I possibly send it to one of you to spray paint it in black for me? I was also considering a powder-coating or something similar to allow the paint to hold, but I have no idea what that would cost, and as this is only a ten dollar container, I don't want to throw hundreds at it. I also won't need a can of spray paint more than once, even though its cheap, and then have it lying around the house unused.

Anyone care to assist me, feel free to PM. Thanks in advance.
