Small claims judgments are appealable, but only if you act very quickly. If you cannot afford an attorney, you should try to do this on your own. If nothing else, you will get a second opportunity to tell your story. If your story doesn't make sense, though (like signing the second contract when you already felt "taken" by the first transaction), you will run the risk of spending the appeal fees, time away from work, etc. -- for the same result. You can also be responsible for their attorney fees if you lose, where most contracts do provide for this, and/or an amount less than $10,000 allows this.
