In your instance small claims court would be the best route. Try not to involve an attorney, you'll end up owing them more than amount your seeking, been there done that. Had a customer who owed me $28K, hired an attorney to go after him legally. I won the case but my now ex-attorney billed me $41K for his services. I was scammed by my own attorney, crook. I now have strong verbiage in all my contracts stating I am the owner of all property listed herein until final payment is made and I reserve the right to repossession. There's some other verbiage that states they will pay for all court costs and attorney's fees if I have to pursue them legally.
That sounds absurd. First off he should have warned you his cost, second that is just excessive, third he could have saved you extensive time and money by going through district court and suing for the maximum in District court. That would have limited costs. Any time a case even appears to cost more than the recovery maximum a client should be thoroughly warned. I'm sorry you had such a bad experience.
