In all honesty, you'll have a difficult time finding another shop that will do custom fabric in such small quantities. Custom fabric is typically very expensive, with minimums starting in the hundreds or thousands of yards, depending on the manufacturing company. That's why Spoonflower has made such a name for itself; at the moment, it's the only place that allows you to make custom fabric in such small quantities. Sorry if that isn't the answer you were hoping for. If you don't want to use Spoonflower, you could try pairing up with someone who does screen printing or works with digital printing to see if they'd be willing to help you out.
