sorry to hear of your mishap. You have a made a few mistakes, and unfortunately they are going to cost you on this occasion, but you will learn from them and be better prepared for the future. First was your insurance policy, if you dont understand it, dont buy it. Find an agent that will explain the policy options, and parts of the policy that you have questions about. I am guessing that you have an acv policy, or maybe modified replacement for major peril. Insurance is a major expences and should be gone over extensivly when shoping policies. There is nothing you can do, but shop for a new plan, posibly an agent. The second is the electrician. Without an initial quote you set yourself up for being over charged. A normal service upgrade, whitch includes a new panel, and mast should cost between 2 to 3k. Its a one day job, and materials cost under 750 dollars which are included in that price. I would ask the electrician for a detailed break down of his time and materials for the project, make him be specific, provide you with recipts, and have your handyman verify his hours. A typical electrician should charge between 75 and 125 an hour. I can normaly rewire a house and have the mast replaced for less than 6k whitch includes around a week of labor and all the materials. In the future find your trades when you dont need them, so you have them for occasions like this. Looking back it will be one of the may educations that you paid for and will be smarter because of it. Good luck.
