Built a new home contract not honored?

Closed on a new home before it was contractualy finished. Builder now says he will not compleat many of the items. What course of action do I have in the State Of New Mexico short of a civil suit? I have contacted NMCID the attorney general page clearly states it will not act on real estate or land matters. I have wrote the Lt Governor. If I go to civil court even when I win there is no assurance that I will recieve the settlement awarded. Can I lean on the builders property? The person representing the construction company does not have a contractors liscense the qualified party I have not even met. What can I do????
