Some of the most pressing problems you need to resolve are:
As soon as possible, you hold a meeting with your friends and the tradesmen present. At the meeting, you come up with the plan that will govern the work on this project over the next year.
With the help of your friends, write out and justify the plan that will be used to govern your work over the next year. This plan will be presented to the commissioning party who is paying all salaries and expenses related to the project. Good Luck!
