I agree with all of your lessons learned. It is particularly amazing how a budget gets thrown out the window. I challenged myself to spend $0 on converting or shed to a multi-purpose coop. I ultimately spent $60 on screws, sockets, bulbs and a sliding barn door kit. I should count the $50 I spent on hardware cloth just prior to starting the project as well that went into it. Fortunately, I had some lumber laying around and a solid structure to begin with. I will need to spend a bit more to finish it I know. I haven't built a new run and I need to finish my quail cages. There will be a few more rolls of hardware cloth in my future.
