How do you go about finding an attorney who will take small cases?

for instance a case of trip and fall (case against the county), product liability (tooth whitener product), etc. The attorneys I've known about will only take huge cases because they want to make money, and I can't blame them for that, however someone has to take the small cases too. Who can we approach to do that. For these kinds of cases we do need attorneys to argue the case for us.
