This is the situation. I am an Engineer, usually working at Construction Project Management.
A friend of mine wants me to present him and his partner a business plan for a small/medium PM company that I would lead. They will be investing 100 % of the money. I will be investing 100% of the work. I will have a salary and they want me to propose to them the profit split I would consider reasonable. The investment should be around 100000 to 150000 $. Since this is a special situation, how much would it usually be fair to ask for.
