Yes, the best option is choosing an electrical company that competently abates inside-wiring defects, in compliance with 406.4(D), and passes inspections for service upgrades, while providing a certificate of additionally insured. Options not typically offered by one-man shops.
While inferior owner-builder permits, or general contractor with laborers doing electrical, may also access plan review & inspections for anticipated defects, AHJ's indemnified from lawsuits can miss buried hazards, and ignore the labor violations, known to cause liability train wrecks for owners.
