Where can I find a coin-counting machine?

Excuse me, could you possibly point me in the direction of a coin-counting machine? I've been carrying around a large amount of loose change and I'm really in need of converting it into bills or depositing it into my bank account. I've tried a few places but haven't had much luck so far. Do you know of any stores, banks, or other establishments in the area that offer this service? I would greatly appreciate any information you could provide. Thank you!
