I don't think I'd call the city until you get an electrician to look at it for you. If the electrical inspector comes out and looks at it, and finds a lot of problems....he may call the power company and have them disconnect the electricity until it's fixed and he re-inspects it. If the electrician can get the power flowing from the bottom of the new meter base that has the meter in it, to the top of that 200 amp breaker in the big panel, and then properly feed the smaller panel from the big one...you should be good to go.
