You have a number of limited choices, and none are perfect. You may attempt to contact a law school near you and seek engagement for representation by a family law clinic, if you qualify. You may seek referral from the county courthouse where you case was filed for pro bono assistance with child support, and/or a referral from the state/local/and/or family law bar association. You may attempt to contact the county child support office and a case worker in the state and county where you ex-husband lives and attempt to record and enforce the foreign (that is what an out-of-state judgment is called) child support judgment in that county via telephone and the mail. You may attempt to enforce the judgment yourself through attending a pro se litigant's clinic in the county in which the judgment was issued. You may solicit low-cost and/or pro bono services from lawyers in your area. And, you may attempt to engage an attorney for collections on the child support judgment under a contingency fee agreement, because even though it is unethical in almost all states to represent a party pre-judgment of divorce for a contingency fee, many states allow the collection of judgments (even child support judgments) under a contingency fee arrangement. The potential contingency fee attorney could be from your state and/or the state your ex-husband lives in. This may seem a tough way to go, but then you're asking an attorney to do work for you, and providing him/her an incentive. $2,150 may seem like a great deal, and I validate on your budget it is, but in the child support arrears world, it is a drop in the bucket. Hope this helps. Good luck.
Contact the child support enforcement department of your local prosecutor's office and ask the to start a reciprocal support enforcement action( URESA ). This may help you get the child support flowing.
