Like Purple-Hops said, I'd try contacting any local shelters/rescues in your area. Especially if you have any small animal/exotic rescues. I know one of my local rabbit rescues commonly also has other small animals like hamsters, rats, degus, etc.
They may not advertise small animals like rodents for adoption as much as they do larger animals. Especially if their main focus is with another type of animal.
Plus if you talk to them, even if they don't currently have any hamsters, most shelters/rescues would be more than happy to keep your contact information and contact you when/if they do have any animals they think you might like surrendered.
