Help–our church building needs work on it and I don’t know where to start

Try Buildings for Mission: A complete guide to the care, conservation and development of churches by Nigel Walter (of our own Ely Diocese), Andrew Mottram available here on Amazon. You could almost call it “Be Your Own Archdeacon”, it’s so good at explaining all the do’s and don’ts, rules and regulations – but keeping a strong sense of the mission of the church in mind as well. Real Archdeacons are a great help too!
