Operate at a small loss for a day and just run Dolce with as many soap as you can carry each voyage until out of energy. After that maybe do optimal runs (33 denaro profit) for a few days to give yourself a Denaro buffer.
Optimal low level daily combination if you are unsure is,
1x Luna voyage with Commerci Soap x2, Organic Leather x1, Stylish Glasses x1.
4x Luna voyages with Commerci Soap x4.
4x Dolce voyages with Commerci Soap x4.
