 If you really want to get cheap/cheat.
 Just build 21 empty base hulls, and design a series of bases, 40% more expensive than the previous, and retrofit all your bases until you work your way up to the core component, plating & cables.
 
 You then pay lots for retrofitting repeatedly, but finish your sphereworld in two turns.
