You will definitely want to seek the advice of an attorney. Just because the at fault driver doesn't have insurance, doesn't mean they are not responsible for damages. If you have a strong case, you may wish to move forward with a lawsuit - to which there may be an out-of-court settlement.
If the person you're planning to sue doesn't have any money, you may just be spinning your wheels because they won't even have the funds to pay any settlement. Choose your battle.
