How much would you assume that all costs?
Less than a 100k for the equipment, tooling and machinery (including small workshop to maintain tooling).
100k for local staff ($300/m trainees, 500-800/m qualified staff).
50k to commission marine engineer to design ship ($500 p/h * 100 hours work).
200k for an industrial plant architect ($1,000 p/h * 200 hours of work).
1 million for bribes and protection money so you can setup in Somalia. Probably more once they see you ship finished products.
50k to rent a warehouse to act as the factory or build one for 150k near the ports for extra security.
Not sure about raw materials and other variable cost since it's Somalia but it won't be more than 10-50k initially.
All in all half a million to get setup and that doesn't include bribes, import tactics, protection money etc.... This is what kills any chance of enterprise in Somalia.
