Home severely damaged by Hurricane Helene. Contractor wants more $, but will not provide proof of expenditures to date.

My home was severely damaged. We resided in temporary locations for 13 months, which were covered by our homeowners’ insurance. However, our lease expired, and we had exhausted all our housing funds. Our contractor had assured us that the house would be ready. The house was not ready. No power to three rooms, construction tools and refuse scattered everywhere, kitchen was not finished, no sink, running water, or countertops. During the reconstruction, we repeatedly requested a detailed account of how he had utilized the funds, but we never received one. Now, he claims that he has run out of money because we chose replacement items that were excessively expensive. However, the truth is that our choices were based on the allocated funds provided by the insurance company. Our verbal agreement with him was that if we upgraded an item, we would be responsible for paying the difference. We have not received an invoice or statement detailing how the funds were spent. Since moving in, we have encountered numerous issues, including electrical, furnace, unfinished kitchen and bathrooms, and many other problems. What kind of attorney should we look for?
